Claus Ibsen resolved CAMEL-19441.
---------------------------------
Resolution: Not A Bug
The child route handles(true) the exception so there is no exception from the
outer route point of view
> Camel does not continue routing after doTry..doCatch..end block in case of
> Direct Component.

> Key: CAMEL-19441
> URL: https://issues.apache.org/jira/browse/CAMEL-19441
> Project: Camel
> Issue Type: Bug
> Components: camel-core, camel-core-api
> Affects Versions: 3.14.7
> Reporter: Harish Annamalai
> Priority: Major
>
> Camel Does not continue routing with a doTry..doCatch..end block with direct
> component with a onException clause defined in it.
> I have created two routes namely, MainRoute and childRoute.
> The ChildRoute consists of an onExceptionBlock, with "handled(true)" clause.
> when an exception occurs in the childRoute, the onExceptionBlock executes and
> the chlidRoute execution stops. However, the flow doesn't continue on the
> mainRoute.
> Camel DSL for the two routes:
> from("timer://runOnce?repeatCount=1&delay=1000")
> .id("MainRoute")
> .onException(Exception.class)
> .setBody(constant("ExceptionBLock"))
> .to("log://error")
> .handled(true)
> .end()
> .setHeader("routeLocation", constant("MainRoute"))
> .setBody(constant("MainRoute"))
> .to("log://main")
> .doTry()
> .to("direct://childRoute")
> .doCatch(Exception.class)
> .to("log://ExceptionCatchBlock")
> .end()
> .to("log://afterTryCatch")
> .end();
> ------------------
> from("direct://childRoute")
> .id("ExceptionRoute")
> .onException(Exception.class)
> .useOriginalMessage()
> .handled(true)
> .setBody(constant("Child Exception Block"))
> .to("log://childExceptionSubProcess")
> .end()
> .setHeader("routeLocation", constant("exceptionRoute"))
> .setBody(constant("Exception Route"))
> .to("log://beforeException")
> .throwException(new RuntimeException("A runtime exception"))
> .to("log://afterException")
> .end();
