JBoss 6.0.0-Final leaks an AsyncInvocationIdUUIDImpl object for every asynchronous call

      Basically, AsyncInvocationIdUUIDImpl fails the following JUnit test:

      @Test
public void testWithConcurrentHashMap() {
    AsyncInvocationId uuid = new AsyncInvocationIdUUIDImpl();
    Map<AsyncInvocationId, Boolean> map = new ConcurrentHashMap<AsyncInvocationId, Boolean>();

    map.put(uuid, Boolean.TRUE);
    map.remove(uuid);

    assertTrue(map.isEmpty());
}

      This same test also fails with Hashtable, although it passes with HashMap and LinkedHashMap.

      Basically, AsyncInvocationIdUUIDImpl fails the following JUnit test: @Test public void testWithConcurrentHashMap() { AsyncInvocationId uuid = new AsyncInvocationIdUUIDImpl(); Map<AsyncInvocationId, Boolean > map = new ConcurrentHashMap<AsyncInvocationId, Boolean >(); map.put(uuid, Boolean .TRUE); map.remove(uuid); assertTrue(map.isEmpty()); } This same test also fails with Hashtable , although it passes with HashMap and LinkedHashMap .

      The AsyncInvocationIdUUIDImpl.equals() method is implemented as:

      @Override
public boolean equals(final Object obj) {
    return uuid.equals(obj);
}

      This implementation is incompatible with ConcurrentHashMap<AsyncInvocationId, Boolean>, which means that AsyncInvocationMap.remove(id) does not remove the AsyncInvocationIdUUIDImpl object from the map at all. In other words, the AsynchronousServerInterceptor.invoke() method is accumulating AsyncInvocationIdUUIDImpl objects until the JVM's heap explodes.
