java - Camel Splitter producing Incorrect Number of Done Exchanges Seen by NotifyBuilder? -

im using camel 2.10.3.

let's assume have route looks following:

from("direct:split")   .routeid("split-ti-analytics-events")   .split().method(jsonarraysplitter.class,"split")   .parallelprocessing()   .log("received: ${body}")   .to("stub:direct:somewhere"); 

and test class following notifybuilder assert splitter doing ought to.

@test(description = "asserts when receive json event split " +             "events if payload json array.") public void testreceivetianalyticsarrayofjsonevents() {     notifybuilder notifier = new notifybuilder(context)       .weresentto("stub:direct:somewhere")       .whenexactlydone(7)       .create();       producertemplate.sendbody("direct:split", sampleeventsinarrayjsonstring);        asserttrue(notifier.matches(5, timeunit.seconds)); } 

and assume sampleeventsinarrayjsonstring json array looks like:

[{},{},{},{},{},{},{}] 

where there 7 object elements in json array.

the test fail pretty immediately. however, output of test shows 7 log messages of "received: {}".

now, here's fun part... in notifybuilder if set .whenexactlydone(8), test passes. on earth 8th message coming from? i'd love test valid , call day since know it's getting @ least messages split off json array (ignoring fact i'm not verifying contents in notifybuilder), i'm concerned having 8th exchange sent through route doesn't belong. reason notifybuilder sees 8 exchanges done through route instead of 7?

yes little bug in camel. have logged ticket, , working fix in tests https://issues.apache.org/jira/browse/camel-6255
