For the moment, I have added this to libCompiler.js in my own node_modules, and it significantly improves compile time with no noticeable side-effects.

See http://docs.oracle.com/javase/7/docs/technotes/guides/vm/server-class.html for difference server/client-class VM

See next output

I have managed to cook a fix for 2nd subcase, but 1st one turned out to be a bit tricky..

Hello,
On MacOSX (and any other system) sometimes one has multiple java versions.
It would be good to be able to override the "java" command easily.
I propose a tiny modification to do this:

diff --git a/lib/libCompiler.js b/lib/libCompiler.js
index b39ea00..9909473 100644
--- a/lib/libCompiler.js
+++ b/lib/libCompiler.js
@@ -56,7 +56,8 @@ compiler.validateFile = function validateFile( fileObj ) {
*/
compiler.compileCommand = function compileCommand( options, fileObj ) {

• var cmd = 'java ' +
• var javaCmd = process.env.JAVACMD || 'java';
• var cmd = javaCmd + ' ' +

This allows you to call
say you have a symlink java17 to a java 1.7 VM...
then you can call:

JAVACMD=java17 grunt...

request.

On my system python defaults to Python 3.

There's a bug in closure-builder that's preventing me from building and compiling at the same time when using Python 3, thus I'd like to switch to Python 2.

Would it be possible to add an option to builder, to specify the python command?
