-------------------------------------
Summary: Failure when using queueless-thread-pool as the pool for a web
connector
Key: AS7-3970
URL: https://issues.jboss.org/browse/AS7-3970
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
This is a piece of log when the error occurs.
