I would say that one Java() invocation maps to one launch of javac.  If you 
give a list of directories to Java(), it handles them all at the same time.  
If you want a lot of javac tasks in parallel, use multiple Java() builders.

Frankly, I don't see anyone using scons for java projects that more 
complicated than "Hello world" or perhaps for testing a JNI implementation 
(which would be useful indeed).
