----------------------------------

             Summary: ClassCastException with ResteasyProviderFactory when including RESTEasy in two WARs
                 Key: AS7-5877
                 URL: https://issues.jboss.org/browse/AS7-5877
             Project: Application Server 7
          Issue Type: Bug
          Components: Class Loading, REST
    Affects Versions: 7.1.1.Final
            Reporter: Eric Wittmann
            Assignee: David Lloyd


Found what I think may be a classloading issue while working on the S-RAMP project.

We include RESTEasy in our WARs because we want a single WAR that runs in multiple containers *and* because we need a newer version of RESTEasy.  If you deploy two WARs that both package RESTEasy, then you will get a ClassCastException.  See the linked RESTEasy Jira issue I entered for this problem (I'm not sure if it's a bug in resteasy or jboss).

Ultimately it seems that a class is loaded from the RESTEasy module included in JBoss AS, despite that module being excluded via the jboss-deployment-structure.xml file.

A sample maven project showing this problem is included on the linked RESTEasy issue.
