[infinispan-dev] parked task?

OK, debuged the problem -- quite similar to ISPN-2232.
I'm reusing an existing cache -- via re-start.
But that cache is first stopped -- transitioning all the way to
LuceneBackendQueueProcessor::close
which calls
LuceneBackendResources::shutdown
which does
flushCloseExecutor( queueingExecutor );
meaning it stops / terminates queueingExecutor.
But once cache is re-started the queueingExecutor is never re-initialized / re-started.
Hence this ThreadPoolExecutor code:
public void execute(Runnable command) {
if (command == null)
throw new NullPointerException();
if (poolSize >= corePoolSize || !addIfUnderCorePoolSize(command)) {
if (runState == RUNNING && workQueue.offer(command)) {
if (runState != RUNNING || poolSize == 0)
ensureQueuedTaskHandled(command);
}
else if (!addIfUnderMaximumPoolSize(command))
reject(command); // is shutdown or saturated
}
}
* runState == TERMINATED !! *
simply puts out command into reject().
And there is nothing to pick it up, as the executor is terminated.
Imo, should be easy to replicate this in Ispn Query tests.
