[CAMEL-13640] Camel Split with Aggregate, calling subroute with onException (handled = true) stops, doesn't work the same way as calling a sub route using doTry

Description

Split  with Aggregate calling a sub route that has handled exception (eq. direct:exceptionStart) doesn't behave the same as one calling a sub route swallowing exceptions using doTry (eq. direct:doTryStart)

The two should be functionally equivalent but the one calling the sub route with onException stops prematurely.   It never gets to ".log("done with split and aggregate").   

Others have reported the same thing on the camel-users list - for example

Sample program attached (maven project) - BugReport.zip

 

public void configure() throws Exception {

from("direct:exceptionStart").routeId("exceptionStart").split(body(), new MyAggregationStrategy())
.to("direct:processItemOnException").end().log("done with split and aggregate");

from("direct:processItemOnException").routeId("processItemOnException").onException(Exception.class)
.handled(true).end().log("${body}").throwException(new Exception("an Error!"));

from("direct:doTryStart").routeId("doTryStart").split(body(), new MyAggregationStrategy())
.to("direct:processItemOnDoTry").end().log("done with split and aggregate");

from("direct:processItemOnDoTry").routeId("processItemOnDoTry").doTry().log("${body}")
.throwException(new Exception("an Error!")).endDoTry().doCatch(Exception.class)
.log("swallowed exception");
}
