      1. Start the AS with -Dorg.jboss.server.bootstrap.maxThreads=3
      You might have to use a higher number for maxThreads (set to 2 + number of persistence units with "hibernate.session_factory_name".)

      OR

      2. Remove "hibernate.session_factory_name" properties from the persistence.xml
      <property name="hibernate.session_factory_name" value="java:global/hibernate/SessionFactory"/>

    Description

      When deploying an EAR with two persistence units on single core machines, the server hangs.
      When increasing the number of cores to two, the same server just works.

      I traced the bug to the method in org.jboss.as.naming.WritableServiceBasedNamingStore.unbind
      The container attempts to register "hibernate/SessionFactory" twice.
      The first time it works, the second time it hangs on the wait statement.

      I suspect a race condition in the ServiceControllerImpl.

          Task - Represents a small unit of work that is not end-user facing. AS7-4934 Provide thread pool for blocking tasks to EE subsystems

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
