Description Robert Taniwa CLA 2009-01-30 15:36:21 EST 
In our adopter product we have a headless batch tool that is experiencing fairly frequent deadlocks. This appears to have started only recently, and looks like it could be related to contention in the Java project/classpath area. Here is a stack obtained via jdb of the hang, and we will be attempting to generate a javacore:

It looks like a dup of bug 249930.
Comment 3 Jerome Lanneluc CLA 2009-02-06 06:34:23 EST 
Marking as a dup of bug 249930 since after I provided a binary patch to Robert, he confirmed that the deadlock problem went away.
