[jboss-jira] [JBoss JIRA] (JBAS-9491) JBoss 6.0.0-Final leaks an AsyncInvocationIdUUIDImpl object for every asynchronous call

[Chris Rankin (JIRA)]

     [ https://issues.jboss.org/browse/JBAS-9491?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Chris Rankin updated JBAS-9491:
-------------------------------

    Steps to Reproduce: 
Basically, {{AsyncInvocationIdUUIDImpl}} fails the following JUnit test:
{code:Java}
@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());
}
{code}

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

> The {{AsyncInvocationIdUUIDImpl.equals()}} method is implemented as:
> {code:Java}
> @Override
> public boolean equals(final Object obj) {
>     return uuid.equals(obj);
> }
> {code}
> 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.
