      1. Build the attached maven project
      2. Deploy the sfsbLock.war in Wildfly
      3. Run the class "CallIt" from src/test/java

      The error can be reproduced in 9 out of 10 calls

      We are having issues with a stateful bean that is invoked serveral times in a request to calculate things. We have a StatelessBean, that is called via REST and calls another StatelessBean which calls the StatefulBean which is request scoped. When we have parallel requests it comes to ConcurrentAccessTimeoutExceptions on the StatefulBean, although we shoudn't have concurrent access since the Bean is request scoped.

      This is the stacktrace we get:

      Caused by: javax.ejb.ConcurrentAccessTimeoutException: WFLYEJB0228: EJB 3.1 FR 4.3.14.1 concurrent access timeout on StatefulBean - could not obtain lock within 5000 MILLISECONDS
