What steps will reproduce the problem?
1. Set up reflections with the following config:
Reflections reflections = new Reflections(new AbstractConfiguration()
{
{
Predicate<String> filter = new FilterBuilder().include(".*");
setFilter(filter);
setUrls(Arrays.asList(new URL[] { new URL(
"<path to some class files eclipse built>") }));
setScanners(new MethodAnnotationsScanner());
}
});
2. Find annotated methods:
Set<Method> annotated = reflections.getMethodsAnnotatedWith(Test.class);
//Junit 4 tests
What is the expected output? What do you see instead?
It all works fine, but the process doesn't die. Reflections creates a
ThreadPoolParallelStrategy that spawns 2 threads (I'm on a dual core
system) in an ExecutorService. There's never a call to shutdown(), so the
threads prevent the JVM from exiting without a system.exit() call.
What version of the product are you using? On what operating system?
trunk version of Reflections... looks current as of 9.29.09
Please provide any additional information below.
To fix it, I added a shutdown() to ParallelStrategy. Reflections.java
should call it at the end of the scan() method. I changed
Jsr166ParallelStrategy to call forkJoinPool.shutdown() (is that correct?
I'm not familiar with those types of pools), SingleThreadedParallelStrategy
does nothing, and ThreadPoolParallelStrategy should call
executorService.shutdown().

What steps will reproduce the problem?
1. Start a JVM on a C drive with a classpath pointing to a directory on the
D drive
2. Try sample code
3. Crash : org.reflections.ReflectionsException: could not create Dir from
url, no matching UrlType was found [file:/D:/<...>]
What is the expected output? What do you see instead?
Drive is stripped during normalization, so absolute file path is resolved
against current working directory (on C drive)

Hi gang,
I found Reflections via an entry in Bill Burke's blog. I see the
Reflections build was created with Maven and was wondering if y'all had any
plans to put to publish it to the central repo? Would be very cool to be
able to get it from there!
Cheers, Brian

File.listFiles() is allowed to return null. Passing it to Lists.newArrayLists()

This causes org.reflections.Reflections#scan to not detect classes in
directories on windows.

Please provide any additional information below.
The bug is in FilterBulder.packageNameRegex(). It should do:
private static String packageNameRegex(Class<?> aClass) {
return prefix(aClass.getPackage().getName() + ".");
}
It's possible the bug is in prefix(); hard to say without Javadoc for prefix()

It seems to me that reflections does not take
java.lang.annotation.@Inherited into account at all.
I'd have expected that when querying types with a specific annotation via
reflections.getTypesAnnotatedWith(annotation) I only get those types that
really declare the specific annotation OR if the annotation is declared
@Inherited, I also get the subtypes of a type that is annotated.
However, with reflections 0.9.2 this behaviour is not working correctly:
1. I tried two different reflection configurations regarding scanners:
a) with both new SubTypesScanner() and new ClassAnnotationsScanner()
b) with only ClassAnnotationScanner()
2. @Inherited is not recognized at all
For 1.a) when querying classes with annotation X all types AND THEIR
SUBTYPES are resolved regardless of whether the subtypes are really
annotated X (not matter of @Inherited specified or not).
IMO this is not correct behavior, subtypes should only be returned if X is
@Inherited.
For 1.b) when querying classes with annotation X only those classes are
returned that really annotated X. However, no matter if annotation X is
marked @Inherited or not, subtypes would not have been resolved.
IMO this is not correct behavior, subtypes should also be returned if X is
@Inherited.
Please contact me if you need further information.
Thanks a lot for your work!

1. use setUrls(ClasspathHelper.getUrlsForCurrentClasspath());
2. create a new Reflections object.

I would expect no output at all. lots of odd output on standard output that
looks like error output.

GNU/Linux
Please provide any additional information below.
I used the following dependency libraries: google-collect-snapshot-20080820
and javassist-3.9.0.
I checked out the source code and found the source of output:
In the JavasistAdapter
public Iterator<ClassFile> iterateClasses(final Collection<URL> urls, final
Filter<String> filter)
...
protected ClassFile computeNext()
...
catch (IOException e) {
System.out.println(e.getMessage());
// throw new RuntimeException(e);
}
I looked into this issue a little more and found why this happens. The
problem is that the virtualFileIterator returns all files (<filename>.*)
and directories(!) on the classpath, only class files should be handled here.
I've added a very lame fix in the attached JavassistAdapter in attachment,
most likely there is a better way.

Reflections.collect should have a Parameter for the path, where it loads its
XML. Until know it is forced, that it is in the Classpath, when you use
Reflections.collect().

Hi, small bug here -
Line 38 in ClasspathHelper:
The test: if (patterns != null)
should actually be: if (patterns !=null || patterns.size() == 0)
Since your recent changes, ClasspathHelper.getUrlsForCurrentClasspath()
returns nothing and I have to work around with
ClasspathHelper.getUrlsForCurrentClasspath(null).
Thanks!

Attached a little patch to support reflections within JBoss 5. It basically
reverts the vfszip and vfsfile jboss url to something that common-vfs would
accept. There is also a test class, that needs some resource in
src/test/resources. I don't know how to include them in the patch, but it
should be quite easy to recreate them.
Thanks a lot for the great work (and version 0.9.4 looks like a huge
improvement).

What steps will reproduce the problem?
1. Configure a Reflections instance as:
Reflections reflections = new Reflections(new AbstractConfiguration()
{
{
Predicate<String> filter = new FilterBuilder().include(".*");
setFilter(filter);
String jarName = "jar:file://"+(new
File(classRepo)).toURL().getPath()+"!/";
setUrls(Arrays.asList(new URL[] { new URL(jarName) }));
setScanners(new MethodAnnotationsScanner());
}
});
Where classRepo is a final String representing a relative path to a jar.
The constructor will fail with an NPE:
Exception in thread "main" java.lang.NullPointerException

What is the expected output? What do you see instead?
I expect for the call to work, resulting in a log message like Reflections
took 375 ms to scan 1 urls, producing 6 keys and 210 values [using 2 cores]
[1 ms per value]
What version of the product are you using? On what operating system?
Latest in the trunk.
Please provide any additional information below.
Looks like Reflections uses URL.getPath around line 150. That causes the
jar: to get knocked off, but the '!' character at the end stays (resulting
in a bad file URL). Using URL.toString instead fixes the issue. This
should probably be tested with jars over a protocol other than file:///
just to be safe.

What steps will reproduce the problem?
1. Include a JAR in the classpath which only contains:
package x.y;
@Documented
@Inherited
@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
public @interface X {
}
2. create an instance with
new Reflections("x.y")
3. an NPE is generated.
What is the expected output? What do you see instead?
Apparently an @interface is not regarded as a class. Thus, in
Reflections.scan(), fileObjects can have a null value,
which leads to the NPE in the call to
ParallelStrategyHelper.apply(configuration.getParallelStrategy(), fileObjects,
scanFileProcedure);
What version of the product are you using? On what operating system?
0.9.4 / Java version "1.5.0_20" / Mac OS X 10.5.8
Please provide any additional information below.
I get round this by only calling ParallelStrategyHelper.apply if fileObjects !=
null

If i remove the build target then the maven pom can find the jar files
okay but as soons as I add the build command it crashes. Any ideas?

I'm trying to filter annotations by value the contain. I have a hierachy of
classes, let's say A<-B (A is a base class), A is annotated with my annotation.
When I do
reflections.getMethodsAnnotatedWith(AnnotationX.class);
I'll get classes A and B as a result.
when I do
reflections.getTypesAnnotatedWith(new AnnotationX() {
@Override
public String info() { return "To be done";}
@Override
public Class<? extends Annotation> annotationType() {
return AnnotationX.class;
}
});
I'll get null pointer exception, because of line:
if
(annotationMap.equals(getAnnotationMap(annotated.getAnnotation(annotationType)))
)
of function getTypesAnnotatedWith(Annotation x)
The problem is, that AnnotationX should influence object B, but is not
present on it, so trying to get value of AnnotationX on class B produces
this Exception.

What steps will reproduce the problem?
1. Try to use reflections under Mac Os X
2. Try to use the ClasspathHelper.getUrlsForPackagePrefix with a package in
a source folder
3. see it fail with runtime exception.
What is the expected output? What do you see instead?
The output should be that the package is recognized, instead a runtime
exception is thrown cos the url representing the package directory is not
recognized as a directory. The failure is in the VirtualFile class
What version of the product are you using? On what operating system?
Version 0.9.2, SO MacOsX 10.5, JDK 1.5
Please provide any additional information below.
I guess the check in the isDirectory method is not working under *nix
systems. I've fixed it with the following change in the VirtualFile class:
public static boolean isDirectory(final URL url) {
final File f = new File(url.getFile());
return f.exists() && f.isDirectory();
}

The Utils.java class uses the System classloader when returning a Set of
scanned classes. It is possible to obtain the Set<String> of class names
implementing a particular interface from the store and create class
instances using a separate classloader. It would be nice if the library
handled it.
One line change in Utils.java takes care of this.
What steps will reproduce the problem?
0. Create SomeInterface.class and create an implementing class.
1. Create a class/jar of the implementing and do NOT add it to the
classpath of the application using reflections.
2. Create a new class loader (extending URLClassLoader) with the URL of the
new jar
2. Set the current classloader to the one created in 2 by
Thread.currentThread().setContextClassLoader
3. Pass the urls to Reflections instance using ConfigurationBuilder
4. Call a method on the reflections instance e.g.
getSubTypesOf(SomeInterface.class)
This is a scenario for dynamic class loading and invoking an implementation.
Output:
Exception in thread "main" java.lang.RuntimeException:
java.lang.ClassNotFoundException: com.test.SomeInterfaceImpl
at org.reflections.util.Utils.forName(Utils.java:41)
at org.reflections.util.Utils.forNames(Utils.java:55)
at org.reflections.Reflections.getSubTypesOf(Reflections.java:222)
Changing the line 39 in Utils.java to:
return Class.forName(type, true,
Thread.currentThread().getContextClassLoader());
loads the class correctly.

Reflections.java contains the following snippet, beggining on line 175:
log.info(format("Reflections took %d ms to scan %d urls%s,
producing %d keys and %d values [%d ms per value]",
time, configuration.getUrls().size(),
configuration.shouldUseForkjoin() ? " [using " +
forkJoinPool.getParallelismLevel() + " cores]" : "",
keys, values, time / values
));
The expression time / values causes an ArithmeticException to be thrown
when values is zero.

What steps will reproduce the problem?
Pass in a package prefix to Reflections.collect which doesn't return any
valid entries. Looks like the underlying problem is that
ClasspathHelper.getUrlsForPackagePrefix correctly returns an empty list,
which gets passed to Vfs.findFiles, but this then returns null.
What is the expected output? What do you see instead?
Vfs.findFiles should return at least an empty list; instead get null and
then a NPE when Reflections.collect tries to iterate

private String resolveOutputDirectory()

String outputDirectory = tests ?
getProject().getBuild().getTestOutputDirectory() :

and use this function to replace the two occurrences of the output

The attached patch uses the strategy pattern for parallel execution, and
includes 3
implementations: Jsr166, a ThreadPool version, and a Single-threaded version
that just runs
everything on the the calling thread.
This eliminates the run-time requirement for jsr166 (though the user can still
opt to use it by
setting the strategy on the Configuration object.)
It also includes some small changes to allow compilation with Java 1.5
(String.isEmpty is 1.6+),
and also fixes a problem in the unit test suite where the xml file was
generated in the wrong
path. Finally, it sets the unit tests to run by default (not sure if there is
a good reason why
they're not running by default?)
I release all this code under the GNU LGPL license (just trying to match the
project- I don't really
care about the actual license!)

ClasspathHelper gets classpath urls of the current URLClassLoader but does not
walk the classloader stack. In my case
(running under Grails) this doesn't wok but walking the stack does. A simple
patch is below.
In a more general case, I think it would be useful to give users a hook to
provide a "find all classes matching a filter"
implementation for custom classloaders.

Using
Reflections-0.9.4
commons-vfs-1.0
jvm-1.5_06
on Windows XP
I get a NullPointerException if I have a jar in my class path.
The reason is:
In the line 150 of Reflections.java you have:
FileObject fileObject = Utils.getVFSManager().resolveFile(url.getPath());
This results for me using commons-vfs.1.0 in the FileObject beeing instance
of ...commons.vfs.provider.local.LocalFile instead of JarFile.
The reason is that url.getPath() returns something similar to
"file:///myjar.jar"
for resolveFile to work it expects "jar:///myjar.jar!"
One solution perhaps could be changing this line to:
FileObject fileObject = Utils.getVFSManager().resolveFile(url.toString());
Also this problem results in null pointer exception in:
line 155:
ParallelStrategyHelper.apply(configuration.getParallelStrategy(),
fileObjects, scanFileProcedure);
This should be changed to:
if(fileObjects != null )
ParallelStrategyHelper.apply(configuration.getParallelStrategy(),
fileObjects, scanFileProcedure);

Lukasz

Then, install it using the command:

2) org.jfrog.maven.annomojo:maven-plugin-tools-anno:jar:1.3.1
3) com.sun:tools:jar:1.5.0
Please provide any additional information below.
The problem is with the POM of the jfrog library that provides a system
path for tools.jar which is not compatible with mac os x (it should point
to ${java.home}/../Classes/classes.jar instead of

Attachments:
In the current version of reflections (0.9.5), the classpath helper doesn't
look at manifests for additional JARs that could be searched for instances
of the target class.
Also the current classpath helper doesn't filter invalid records (one's
that don't have a corresponding URL type in the vfs classes).
I've attached a patch that I used to work around the issue (it could use a
little clean-up, but it works).
What steps will reproduce the problem?
1. For the manifest issue, use reflections looking for classes in dependent
jars.
2. For the filtering URL problem, the most reliable way to reproduce it is
to run it on Mac OS X (which by default adds a zip to the classpath on each
machine I tested).
What is the expected output? What do you see instead?
No classes are found in the manifest case, and the system will exception
out in the filtered URL situation.
What version of the product are you using? On what operating system?
0.9.5 RC1 on both OS X 10.5 and 10.6, and various linux distros.
Please provide any additional information below.
Thanks for the great library! It's really appreciated, and let me know if I
can do anything to recraft the patch.

If reflections encounters an executable jar with a classpath entry embedded in
the manifest, it
can't find classes pointed to by that classpath manifest entry.
What steps will reproduce the problem?
1) Open the attached sample.
2) Run ant, altering / overriding the parameter lib.dir to point to your
external dependencies.
3) Run the sample using java -jar ClassFinder.jar.
4) Edit the build.xml to move TestImpl.class into ClassFinder.jar.
5) Rerun the sample using java -jar ClassFinder.jar.
6) Reflections can now find the jar.
What is the expected output? What do you see instead?
Expected:
Reflections found class: TestImpl
Success finding TestImpl class on classpath
Actual:
Unable to find class using reflections
Success finding TestImpl class on classpath
What version of the product are you using? On what operating system?
0.9.5-RC1 on SuSE Linux.
Please provide any additional information below.

[deleted issue]
What steps will reproduce the problem?
1. Create an example class:
package org.example;
public class Example
{
@Deprecated
public void printIds(long[] ids) {
for (long id : ids) {
System.out.println("id = " + id);
}
}
}
2. Create an ExampleTest class:
package org.example;
import org.junit.Test;
import org.reflections.Reflections;
import org.reflections.scanners.MethodAnnotationsScanner;
import org.reflections.util.AbstractConfiguration;
import org.reflections.util.ClasspathHelper;
import java.lang.reflect.Method;
import java.util.Set;
public class ExampleTest
{
@Test
public void test()
throws Exception
{
Reflections reflections = new Reflections(new AbstractConfiguration()
{{
setUrls(ClasspathHelper.getUrlsForPackagePrefix("org.example"));
setScanners(new MethodAnnotationsScanner());
}});
Set<Method> methods =
reflections.getMethodsAnnotatedWith(Deprecated.class);
for (Method method : methods) {
System.out.println("method.getName() = " + method.getName());
}
}
}
3. Run the test
What is the expected output? What do you see instead?
I expect to see "printIds" printed to standard out. Instead I get:
