Subject [jira] [Created] (CAMEL-7351) NPE in CamelInternalProcessor
Date Tue, 08 Apr 2014 14:06:21 GMT
Richard O'Sullivan created CAMEL-7351:
-----------------------------------------

             Summary: NPE in CamelInternalProcessor
                 Key: CAMEL-7351
                 URL: https://issues.apache.org/jira/browse/CAMEL-7351
             Project: Camel
          Issue Type: Bug
          Components: camel-core
    Affects Versions: 2.12.2
         Environment: CamelContext executing in https://github.com/hawtio/hawtio-camel-wiki
Deployed to apache-tomcat-7.0.47
Hosted on Ubuntu Linux 13.10
            Reporter: Richard O'Sullivan
            Priority: Minor


Using Trace mode in Hawtio throws NPE when route uses <onException> to handle a business
exception. Trace mode is successful (no NPE) when the route does not throw a business exception
(i.e. route is successful).

I suspect that the value of routeDefinition in BacklogTracerAdvice is null when <onException>
handles an exception.

{code:java|title=CamelInternalProcessor$BacklogTracerAdvice}
public BacklogTracerAdvice
(
    Queue<DefaultBacklogTracerEventMessage> queue, 
    BacklogTracer backlogTracer,
    ProcessorDefinition<?> processorDefinition, 
    ProcessorDefinition<?> routeDefinition, 
    boolean first
)
{code}

{code:none}
org.apache.camel.processor.CamelInternalProcessor
522		String routeId = routeDefinition.getId();
{code}

{code:none}
