             Summary: 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


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();}}{{ }}
