Simple collections as part of Documents about jsondb-core HOT 2 CLOSED

Hi @oiale

Arrays.asList("A", "B") returns a object of type Arrays$ArrayList```

Arrays.asList returns a List implementation, but it's not a java.util.ArrayList. It happens to have a classname of ArrayList, but that's a nested class within Arrays - a completely different type from java.util.ArrayList

Also JsonDB uses XMLEncoder internally to create a deep copy of objects before processing them. However Arrays$ArrayList does not serialise properly, thats probably because XMLEncoder requires it to be a valid JavaBean, meaning among other things it should have a default public constructor which Arrays does not have

So the way you are using it, its not going to work. To workaround this issue I suggest you create a proper java.util.List and then set it into the bean:

List<String> stuff = new ArrayList<String>(Arrays.asList("A", "B"));
bean.setStuff(stuff);

This should work, i added a unit test to test this and it passes just fine.

The latest build on Maven Central is: 1.0.64

from jsondb-core.

Thank you, the issue is resolved. Do you have a wiki that you could put this on?
