JBoss AOP deadlocks on JBoss AS with pluggable instrumentor
-----------------------------------------------------------

                 Key: JBAOP-794
                 URL: https://jira.jboss.org/browse/JBAOP-794
             Project: JBoss AOP
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 2.2.1.Alpha2, 1.5.6.GA, 1.5.5 CP04
            Reporter: Flavia Rainone
            Assignee: Flavia Rainone
             Fix For: 1.5.7.GA, 2.1.6 CP01


JBoss AOP deadlocks in loadtime weaving mode on JBoss AS.
This is the scenario:
-one thread loading a class starts loadtime weaving. In the process, the classloader performing the loading is locked. The thread ends up needing a concurrency lock held by the other thread.
- another thread loading a class also starts loadtime weaving. In the process, this threads locks one of the concurrency locks and ends up needing to load a class (JBoss AOP or Javassist class). For loading this class, however, this thread needs the class loader lock held by the first thread.
