Thanks for your quick reply (and for a great product :-) ) ! I tried out the fix, and it seems to be working. However, trying a few runs, one of them still seemed to hang as before. This didn't happen again, though... I'm trying to create a simple program to reproduce the bug (using the old jboss-aop version), but as of yet it doesn't reproduce using this small program (the original program is a large application, depending on quite a few native libraries, so it won't be of help as a test case). I'll post here if/when I've news on this one. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3989232#...
