Release Regression From : 5.0
The above release value was the last known release where this 
bug was not reproducible. Since then there has been a regression.
Comments
SUGGESTED FIX we should only apply the null check if ld is applicationDescriptor ? this seems to fix the bug: if(ld.isApplicationDescriptor() && null==selectedJREDesc) { throw new InternalError("selectedJREDesc null"); }
05-09-2008
EVALUATION Problem is in DefaultMatchJRE.java, method endTraversal, it always assume we will get a selectedJREDesc: if(null==selectedJREDesc) { throw new InternalError("selectedJREDesc null"); } So in this case, we are parsing an extension-ld with no <resources> in it, and hence selectedJREDesc is null.
