[~davsclaus] : Thanks for your response. I apologise for re-opening the issue,
as I feel the bug report was not properly presented.

That is if the childRoute doesn't have any exception handling, the doCatch in
mainRoute executes, and the mainRoute also continues execution.
If the childRoute, has exception handling, the mainRoute also stops execution.
What I feel like a bug is, the regardless of the exception handling in
childRoute, the mainRoute needs to continue. Here, the mainRoute also stops
execution.
In java, the code after the try..catch executes in the calling block, after the
catch block, but this doesn't seem to be the case with doTry..doCatch

> 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();
