> NPE using seda (with concurrentConsumers) and stream endopoints
> ---------------------------------------------------------------
>
> Key: CAMEL-4581
> URL: https://issues.apache.org/jira/browse/CAMEL-4581
> Project: Camel
> Issue Type: Bug
> Affects Versions: 2.8.1
> Reporter: Lorenzo Luconi Trombacchi
> Assignee: Willem Jiang
> Priority: Minor
> Fix For: 2.7.5, 2.8.3, 2.9.0
>
>
> I found an issue with seda and stream endpoints.
> Using more then 1 concurrent consumers for seda and using "stream:out" as
> destination endopoint , I sometimes receive some NullPointerExceptions.
> This is how to reproduce the problem:
> context.addRoutes(new RouteBuilder() {
> @Override
> public void configure() throws Exception {
> from("seda:sendRequest?concurrentConsumers=10")
> .to("stream:out");
> }
> });
> context.start();
> for ( int i = 0; i < 50000; i++ ) {
> producer.sendBody("seda:sendRequest", String.format("Message %d",
> i));
> }
> And this is one of the exceptions:
