NullPointerException while shutting down EmbeddedJBoss Beta3

NullPointerException while shutting down EmbeddedJBoss:

This happens because aspectManager is set to null, before undeploying AspectManager.
While debugging I detected that BeanMetaDataDeployer undeployment process is causing this:

[alesj]

Like I said on JIRA, AspectDeployer has been fixed since Beta3, so if you can try current version of it, that would be great.

[alesj]

Or perhaps - looking at the error - might be a configuration error: something in ejb3-deployers-beans.xml is unsetting aspect manager on aspect deployer, while it's still used.
Where is AspectDeployer configured/described?

[drorb]

Aspect deployer is configured in aspect-deployer-beans.xml:

<?xml version="1.0" encoding="UTF-8"?>

<!--

 </bean>

</deployment>

As I wrote before, while debugging I see that the one who nullify the aspectManager is BeanMetaDataDeployer

No, that's just because BMDD is undeploying that ejb3-deployers-beans.xml, where it uninstalls some bean that unsets aspect manager.

So, we're looking for the bean that does that unset. ;-)

[drorb]

Sorry, I'm not sure I got you.
From the stacktrace and from debugging I see that BMDD is undeploying the AspectDeployer deployment unit.
The unsetting of aspectManager is done in the undeployment process by ConfigureAction.uninstallActionInternal(...).

BMDDeployer is responsible to uninstall BeanMetaData instances from Controller.
A BMD corresponds to a bean that is installed in Controller.
So, when BMDD does undeploy, that bean is unwinded, meaning that while in ConfigureAction at uninstall phase it nullifies previously set properties, one of them being aspectManager.

OK, you can say that it originates from BMDD, but than you can say that it originates from bootstrap classloader. ;-)

[drorb]

Could the problem be the order of undeployment?
Does it have any relation to parentFirst vs parentLast undeployment?

Dunno.
But have we identified that unsetting bean yet?

[drorb]

How can I find it?

[alesj]

Better logging - trace level?
Or post the ejb3-deployers-beans.xml, might be obvious.

Hmmm ... nothing obvious about that.
Let's see the trace log. :-)

[xnejp03]

I have the same problem, anyone got a solution to this?

[kenundrum]

Bump on this topic, is somewhat important to fix IMO. Anyone have an answer yet?
