Cannot handle Exception thrown from Splitter Expression

[s_albrecht]

After I upgraded from camel 2.2.0 to 2.5.0 I found an issue with exceptions thrown by splitter expressions.
These exceptions are neither caught by route local error handlers nor by global error handlers. Is this a feature or bug ?
See attached JUnit for details.

Hi

Thanks for reporting.

The issue is that the exception occurs in the evaluate of the
expression which happens before Camel routes the splitted message.
Then the exception is caught by the splitter EIP and it regard the
exception as being exhausted. And therefore the onException doesn't
kick in.
Camel assumed the exception was exhausted (which isn't the case).

I have created a ticket
https://issues.apache.org/jira/browse/CAMEL-3394

I think I've found a similar case when the exception occurs within a split().method()

In this case, the exception is thrown inside the method() and doesn't make it to the onException() handler.
Adding a .onException() into the direct://testsplitter route doesn't seem to make any difference.

Is this indeed a bug?

I've had this same issue, just haven't had the time to look into it or
reproduce it in isolation.  split().method(...).  I ended up putting a
try/catch/log in my splitter method code, which was sufficient for my
purposes.

Your test produces a similar situation to mine. Since Claus Ibsen fixed this in 2.6.0 trunk, I regard this as a bug, not as a feature. Unluckily I did not have the chance yet to verify the fix. I am still stuck with 2.5.0, there is the workaround of try - catch in the splitter method.

I'm using 2.6.0 and your problem is indeed fixed.
While the try/catch works for my purpose, it means that I can't use onException where it does work and have to implement try/catch there as well.

Is the bug I reported going to be accepted into jira?

I have exactly the same problem with camel-core (2.7.1.fuse-00-43) running inside fuse-esb 4.4.0-00-43.

I am using the split().method(bean, methodName) syntax and my exception is not picked up by the handler.

Can we reopen the JIRA ticket?

Yes I have fixed it today.

Will be ported to Fuse in the 2.8 and 2.7 branches, so it will be in
the next release of Fuse Camel.
