             Summary: CLONE - Failure when using queueless-thread-pool as the pool for a web connector
                 Key: AS7-3971
                 URL: https://issues.jboss.org/browse/AS7-3971
             Project: Application Server 7
          Issue Type: Bug
          Components: Server, Web
    Affects Versions: 7.1.0.Final
            Reporter: Brian Stansberry
            Assignee: Jason Greene


User is reporting a failure when configuring a queueless-thread-pool as the pool for a web connector.

The report is for a SIGSEGV but I believe that is just because the native connector is being used; if it weren't this would just show up as a normal java exception.

The relevant code in QueuelessExecutor is here:

if (executor != null) {
    executor.execute(task);
} else {
   throw new RejectedExecutionException();
}

The exception is thrown because 'executor' is null. We'll need configuration information from the user to understand why that is the case.

Here's the user report:

SIGSEGV occurs when specify queueless-thread-pool to executor of connector
