I have 2 threads, each issuing a Class.forName ()
through the following util:
public static Class forName (final String className)
throws ClassNotFoundException {
final Thread currentThread = Thread.currentThread ();
final ClassLoader classLoader =
currentThread.getContextClassLoader ();
final Class newClass = classLoader.loadClass
(className);
return newClass;
}
I get a deadlock in the JBoss LoadMgr quite regularly
during startup.

for it. so this is just to generate the notification.

I'm going to need the trace level log as described in the
docs section on class loading debugging.

i attached LoadMgr.nextTask.deadlock.txt in the original post.
it contains the traces of 2 threads stuck in LoadMgr.nextTask
()
if you need something different, just shoot & i'll get it to you.
