Before jigsaw is integrated in jdk7, we will create one jar per module as part of the modularization effort. Since the list of modules is not finalized, we will temporarily modify the launcher to detect if this is a module image and enumerate the list of modules to add to the bootclasspath.

This should not impact the normal JDK/JRE build. The launcher should only alter the bootclasspath if jre/lib/rt.jar doesn't exist and classes directory doesn't exist.
