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
Priority: Minor
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:
2011-10-25 10:12:36,550 ERROR [org.apache.camel.processor.DefaultErrorHandler]
