> ThreadsProcessor configured with ExecutorService with DiscardPolicy or DiscardOldestPolicy leaves inflight exchanges for discarded tasks unprocessed.
> Here is the code from ThreadsProcessor. In case of DiscardPolicy or DiscardOldestPolicy executorService will no throw RejectedExecutionException, so exchange remains unprocessed and count of inflight exchanges will not be decremented for such discarded exchanges.
> {code:java|title=ThreadsProcessor#process(Exchange, AsyncCallback)}
> public boolean process(Exchange exchange, AsyncCallback callback) {
> if (shutdown.get()) {
> throw new IllegalStateException("ThreadsProcessor is not running.");
> }
> ProcessCall call = new ProcessCall(exchange, callback);
> try {
> executorService.submit(call);
> // tell Camel routing engine we continue routing asynchronous
> return false;
> } catch (RejectedExecutionException e) {
> if (isCallerRunsWhenRejected()) {
> if (shutdown.get()) {
> exchange.setException(new RejectedExecutionException());
> } else {
> callback.done(true);
> }
> } else {
> exchange.setException(e);
> }
> return true;
> }

> {code}
> Unit test is attached.
