My first JDK bug
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6546113
Hopefully, in a month or do, I’ll be able to do something about it. Like fixing it. 
In the meantime I created a Mauve test that covers this and fixed up the GNU Classpath implementation (which didn’t fail in this particular case, but screwed on a much higher level).

The problem is caused by the change for 4997655 in jdk6. We need to fix this in an 6.0 update too.
