Hi, using JBoss 5.0.1GA I get the following error sometimes: | ERROR [STDERR] (AOPListner) Exception in thread "AOPListner" | ERROR [STDERR] (AOPListner) java.util.ConcurrentModificationException | ERROR [STDERR] (AOPListner) at java.util.WeakHashMap$HashIterator.nextEntry(WeakHashMap.java:762) | ERROR [STDERR] (AOPListner) at java.util.WeakHashMap$KeyIterator.next(WeakHashMap.java:795) | ERROR [STDERR] (AOPListner) at org.jboss.aop.AspectManager.getAdvisors(AspectManager.java:540) | ERROR [STDERR] (AOPListner) at org.jboss.console.plugins.AOPLister$RefreshPoller.run(AOPLister.java:891) (This log snippet is complete, there are no more log rows related to this issue) I've seen this in the boot.log during startup; it doesn't appear to affect execution (AFAIK). I didn't change anything at the jboss configuration level, besides deploying some applications. Should I open a JIRA? (it is 2.0.1.GA right?)
