WAR deployment fails due to NPE when both MBean and persistence-unit are packaged in one war on JBoss EAP 7.2

Solution Verified - Updated

Environment

  • Red Hat JBoss Enterprise Application Platform (EAP)
    • 7.2.x

Issue

When a web application contains both MBean (jboss-service.xml) and persistence-unit (persistence.xml), the WAR deployment fails due to the following NullPointerException on JBoss EAP 7.2.x. The same application can be deployed on JBoss EAP 7.1.x.

Resolution

This is a bug that has been reported as the following JIRAs and has been fixed in JBoss EAP 7.2.6 onwards:

To work around this issue, you can separate MBean (jboss-service.xml) and persistence-unit (persistence.xml) to different application archives, or package MBean (jboss-service.xml) as SAR archive.
