kill -3 on the Java process should cause it to do a thread/stack dump,
which may prove useful.

Another thing you can try is running java with -Xrunhprof:depth=8, though
note that this will have a significant impact to performance.  It will,
however, produce stack traces (of depth 8 in this case) for each thread
when you kill the JVM normally (not with kill -9).
