Subject: Re: Possible threading issue
Thanks for the feedback, I've reviewed the references you pointed out and
decided to simplify the route.
I have remove all of my .threads(...) DSL calls. I only use parallelProcessing
in 1 place now and I am still running into the problem.
Below is a version that fails and one that works because a threads(1,1) makes
it single threaded at 1 point.
This route throws the NullPointerException:
ExpressionNode resultDefinition = routeDefinition.split()
.tokenizeXML(GenericTMCXMLProcessor.FLOW_TAG_DELIMITER).streaming()
.parallelProcessing().timeout(timeout)
.process(new GenericTMCXMLProcessor(appGlobals, jobProps))
.split(genericTmcMappingProcessor)
.process(preDestinationProcessor);
.multicast()
.to(destinationURIs);
This version works:
ExpressionNode resultDefinition = routeDefinition.split()
.tokenizeXML(GenericTMCXMLProcessor.FLOW_TAG_DELIMITER).streaming()
.parallelProcessing().timeout(timeout)
.process(new GenericTMCXMLProcessor(appGlobals, jobProps))
.split(genericTmcMappingProcessor)
.process(preDestinationProcessor);
.threads(1, 1)
.multicast()
.to(destinationURIs);
