Doc Text:
An issue that could result in a NullPointerException has been resolved in this release of JBoss EAP 6. The exception could present when a deployment partially restarted some data structures that were required have already been cleaned up to save memory (for example, when a dependency was replaced). This issue would prevent the redeployment from completing. To address this issue, partial redeployments are no longer allowed in this release of the product. If a dependency is replaced the deployment is now completely restarted and the exception no longer presents.

Description Stuart Douglas 2013-03-22 04:37:36 UTC
If you have a deployment that dependends on another deployment (either using inter deployment dependencies or a class loading dependency) and you replace the dependee deployment then the dependent deployment will fail to restart.

This is now resolved for non OSGi deployments. At the moment I can't see any way to achieve the desired OSGI behaviour without a redesign of how DUP's work.

I'm moving this out of "Pull Request Sent" status but not to "Resolved" because AIUI the fix did not fully resolve the reported issue. I'll leave it to you guys to sort out what the next step is.

Comment 3 Stuart Douglas 2013-03-29 21:28:59 UTC
This is resolved for non-OSGi deployments. I think we should resolve this issue and create a new one for the OSGi problems, as the OSGi issue is not so much caused by dependency changes but rather by explicit start/stop operations on the bundle.
