WAR MDB cannot obtain superclass on module classpath ---------------------------------------------------- Key: WFLY-4200 URL: https://issues.jboss.org/browse/WFLY-4200 Project: WildFly Issue Type: Bug Components: Class Loading, EJB Affects Versions: 8.2.0.Final Reporter: John Mazzitelli Assignee: David Lloyd Priority: Minor Attachments: mdb-test.zip see the forum post for details: https://developer.jboss.org/message/914355 but suffice it to say this is similar to https://issues.jboss.org/browse/AS7-2638 which appears to have come back again. In my WAR, I have an MDB which extends a class (in which that superclass implements MessageListener) and that superclass is in a module that my WAR depends on; the MDB fails to deploy. I have to explicitly add an annotation attribute to workaround the problem. Again, see the forum for the very easy steps to replicate with a small zip file that contains the replication code.
