I used to think that the java package was incompatibile with GCJ, but now I have changed my mind. I experience the same valgrind errors with both OpenJDK 6/7 and GCJ. My current hypothesis is that the java package creates invalid pointers in some Java objects, and whether and where this leads to a crash depends on the JVM implementation; this would explain why I was not experiencing crashes with OpenJDK 6, while I do now with OpenJDK 7. Of course I understand very well that as long as you cannot reproduce it, you can't fix it. Maybe you've already tested that, but are you able to replicate the valgrind messages?
