Possible bug in JBoss 3.2.3

[apinto]

Hi there,

I'm noticing a strange behaviour in JBoss 3.2.3. When an undeployment is immediatly followed be a deployment, the following exception occurs:

Caused by: java.lang.NullPointerException

In the application, I'm trying to create a connection from a DataSource to an Oracle database. I've inspected LoadMgr3.java:119 and a NPE can only occur if "task" or "repository" are null. Has anyone experienced the same error? Thanks in advance,

Please file a bug report on this.

This occurs when another deployment is using stale classes from deployment which has been replaced. In this case, the jdbc driver container deployment has presumably been redeployed which the datasource configuration has not.

Has this been posted as a bug? I have searched the sourceforge bug page but can't find a reference to it.

I ask because I am having a similar problem in JBoss 3.2.3 (i.e. I have an MBean in a SAR and an app in an EAR that share a common jar... everything works fine from a cold startup until you try and hot re-deploy the SAR... the NPE is thrown as described above).

Note the problem goes away if I put the shared jar in server/default/lib instead, but isn't this generally bad practice?

Thanks in advance.
