[jira] [Reopened] (CAMEL-11664) Split proceeds even if onPrepare throws Exception

["Christoph Läubrich (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CAMEL-11664?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Christoph Läubrich reopened CAMEL-11664:
----------------------------------------

This don't fix it. If the prepare fails and the split fails it might break out but you have no idea why your prepare was never called since the exception is completely ommited!
In case where the missing onprepare does not lead to an exception in the split the split succeeds and is performed with wrong/unprepared data.
Think of a switch with a default case inside the split, the on prepare computes a value used in the switch.
If onPrepare fails, the splitt completely succeeds but always fall through to the default case without any notice. This is a real pain to debug and prone to unnoticed errors.

Wha is it considered as "not a problem" when Camel silently ignores this case?

> With the [splitter|http://camel.apache.org/splitter.html] you can set an onPrepareRef to allow custom preprocessing.
> If this processor fails with an exception, the splitting still proceeds leading to hard to track problems becuase the splitter receives messages that are not (or only partially) prepared! Even setting an exception does not let camel fail the split.
> If the prepare step fails camel should fail the split with the exception thrown from onPrepare.
