Error description
If multiple JAXRS applications are installed in a WebSphere Application Server server, stopping one of the applications may cause the remaining JAXRS application to become unusable with a NullPointerException generated in the logs

Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server with multiple JAXRS applications * * within a single server. * **************************************************************** * PROBLEM DESCRIPTION: Stopping one of multiple JAXRS * * applications can cause others to * * become unusable. * **************************************************************** * RECOMMENDATION: * **************************************************************** This problem only occurs when multiple JAX-RS applications are started within the same WebSphere server. The issue is triggered when one of the applications, other than the first one started, is stopped. This will cause the first application, that is still running, to become disabled and a NullPointerException will appear in the logs. Upon analysis we determined that certain resources that were associated with the first application started were mistakenly removed when other applications were stopped. The resolution to the problem was to change the code that executed at application stop to remove only those resources associated with the application being stopped.
Problem conclusion
The fix for this APAR is currently targeted for inclusion in fix pack 9.0.0.5. Please refer to the Recommended Updates page for delivery information: http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
Temporary fix
This issue can be worked-around by stopping and restarting the WebSphere Application Server process.
