I encountered the hang in latest jdk1.6.0_20 version.

I tried to get the threads dump, but both jstack and kill -3 didn't produce
any results.
Below is the GDB dump:

Earlier in this thread I receive that possible cause is the dlsym function
in libdl library. I googled a bit for similar issues, and found only the

I also received advices to:

* ReduceInitialCardMarks
* UseBiasedLocking

Which one of them may solve the issue, and what the possible results would

Thanks in advance.
