[jboss-dev-forums] [JBoss Microcontainer Development] - Re: Potential deadlock in ClassLoaderManager

No the problem is on line 205 - unless the first thread with the add() is looping.

It looks like a missed notification since nothing is holding the lock?

  | "Thread-2" prio=10 tid=0x83113800 nid=0x443e in Object.wait() [0x833b2000]
  |    java.lang.Thread.State: WAITING (on object monitor)
  | 	at java.lang.Object.wait(Native Method)

  | 	at java.lang.Object.wait(Object.java:485)

If you can reproduce it, can you turn up the logging for
org.jboss.detailed.classloader.ClassLoaderManager
to TRACE.
