ConcurrentModificationException during JBoss 5.0.1.GA startu

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?)

Hi!

Thanks for letting us know!

Taking a look at the code however, I don't think that this error should be occurring with the new version. Could you please download the latest version from http://www.jboss.org/jbossaop/downloads/ and give it a try?

To install it in your AS, take a look at the jboss-50-install folder (you just need to edit the properties file and run ant). Please, if the error still persists, let us know or open a JIRA.

Hi Flavia,
thanks for the kind answer; you're right it's not a problem any more.

Hi Everybody!

I am having the same problem!!

http://www.jboss.org/index.html?module=bb&op=viewtopic&t=163972

The last stable version is with a problem to download

ERROR: No such category: jboss-aop-2.1.6.GA.zip

Someone have other link?

Also, This must be compiled? can anyone give me some instruction or manual about how to install / upgrade this on jBoss? PS: i not developer, i'm the operations guy =))

It seems I screwed up when uploading 2.1.6.GA, I'll try to do that tomorrow. However, 2.1.5.GA should also contain the bug fix.

FYI: I just came across this error using JBoss 5.1.0.GA:

Hi All,
It is now 2013 and I'm running jboss-5.1.0.GA and I am getting the same exception with the same line numbers:
2012-09-13 16:53:24,379 ERROR [STDERR] (AOPListner) Exception in thread "AOPListner"

If anyone knows a work around that would be helpful.

Thanks,

Andrew

I ran into the same error message as above (except date and time :-)) with the same JBoss version

I found my mistake: I had to use the JBoss version with JDK6 (I usesd the other one).
