[Bug java/15768] New: ICE: blowing stack with seemingly infinite recursion in jc1

["green at redhat dot com" <gcc-bugzilla at gcc dot gnu dot org>]

This appears to be a stack-overflow problem.  I hit it while building
src/org/apache/xerces/dom/ASDOMImplementationImpl.java to native code from the
xerces in rhug. 

This problem doesn't happen if you build this file first (ie. there are no other
class files yet).

Just check the code out from sources.redhat.com:/cvs/rhug (module rhug/xerces),
configure and build to reproduce.
