StackOverflowError when org.jboss.as.jacorb.rmi.InterfaceAnalysis is analyzing javax.ejb.EJBObject -------------------------------------------------------------------------------------------------- Key: WFLY-2920 URL: https://issues.jboss.org/browse/WFLY-2920 Project: WildFly Issue Type: Bug Security Level: Public(Everyone can see) Components: IIOP Affects Versions: 8.0.0.Final Reporter: Osamu Nagano Assignee: Stefan Guilhen Attachments: td.dump Depending on when a thread context switch happens, an IIOP enabled EJB fails to be deployed by throwing {{java.lang.StackOverflowError}}.

The same stack has been appeared in a different MSC service thread which is also executing an IIOP enabled EJB deployment. The customer identified an improper synchronization in {{org.jboss.as.jacorb.rmi.WorkCacheManager#getAnalysis()}}. It is reproducible by manually controlling a thread context switch using a debugger.
