> Hi, 
> We noticed after switchting from cxf 3.1.7 to 3.2.x that our application is 
> not starting anymore.
> After some analysis we found out that the cxf module 
> cxf-rt-rs-security-oauth2 contains a class 
> org.apache.cxf.rs.security.oauth2.grants.code.JPACMTCodeDataProvider which 
> injects an EntityManager using @PersistenceContext without defining a 
> unitName. On our JBoss 6.4 EAP (JBoss 7.x) we get the following error 
> message: 
> {code}
> java.lang.IllegalArgumentException: JBAS011470: Persistence unitName was not 
> specified and there are x persistence unit definitions in application 
> deployment deployment
> {code}
> With only one persistence unit definition it's working, but we need multiple 
> PU's.
> One solution I have in mind is to define a unitName for the 
> PersistenceContext on the 
> org.apache.cxf.rs.security.oauth2.grants.code.JPACMTCodeDataProvider 
> ("CXF_PU") , so that a PU has to be define explicitly in the persistence.xml, 
> I mean it's not nice but for us it would be ok. 
> Or perhaps there are other macanisms to avoid the persistence context 
> injection if this class is not used? 
> It currently prevents us from switchting to the newest cxf version.
> I attached a sample maven project to reproduce this issue on a JBoss 7.x .
> Greetings, Olivier
