I am using JBoss [WonderLand] 3.2.5 (build: CVSTag=JBoss_3_2_5 date=200406251954) , Java version: 1.4.2_05, Is it fixed ?

A potential issue looking at this trace is that since your going into the JCE layer, there might be caching of the previous classes and they are using their original class loader which has been destroyed. Unless all references to the previous deployments classes are free to be garbage collected, there is the potential for the NPE when additional classes need to be loaded when access the previous version classes. -- Comment By: Jason Calabrese (jcalabrese) Date: 2004-01-30 18:47 Message: Logged In: YES user_id=300014 I'm having the same problem with 3.2.3.

UnifiedClassLoader3, line 118 does a null check for repository just a few lines before calling loadClassImpl, so I'm assuming that this is a valid state for the class loader to be in. That would mean that beginLoadTask in LoadMgr3 needs to handle the situation where repository is null. -- >Comment By: Scott M Stark (starksm) Date: 2004-01-20 14:45 Message: Logged In: YES user_id=175228 So where is the com.mysql.jdbc.Connection class coming from in the deployment, and has there been a redeployment of anything in the encompassing deployment? The current 3.2 codebase has additional debug level logging to track when a class loader is removed from the repository as well as a fix for delaying the removal of a class loader from its repository until the top level deployment have been destroyed. -- Comment By: Tim McCune (javajedi) Date: 2004-01-20 12:22 Message: Logged In: YES user_id=62441 Ok, stack trace attached. -- Comment By: Scott M Stark (starksm) Date: 2004-01-15 04:54 Message: Logged In: YES user_id=175228 Add the full stack trace as an attachment so I can see where the load attempt is originating from. An NPE in LoadMgr indicates that the UnifiedClassLoader3 has been removed from the repository in between the loadClass class and the delegation to LoadMgr. The only cause of this would be destruction of the associated deployment due to a redeploy. -- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=376685&aid=877172&group_id=22866 --- The SF.Net email is sponsored by EclipseCon 2004 Premiere Conference on Open Tools Development and Integration See the breadth of Eclipse activity.

I'm still not sure exactly how to reproduce it, but since it's an NPE, I'm hoping that someone can track down what would cause it to happen fairly easily.
