I have some problems with IDEA not being stable any more after resuming on my Linux box. So I have to close IDEA first before hibernate. I have made some tests with an other Java application and it had some problems as well. So I assume it is really related to JDK core (1.6.0_20). I am curious if you know this problem (did not find something in java bug database) and if you have probably some tips or a workaround?
