[jira] [Updated] (CAMEL-8871) null body after exception from transform method

["Hans Orbaan (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CAMEL-8871?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Hans Orbaan updated CAMEL-8871:
-------------------------------
    Attachment: ExceptionToErrorRouteTest.java

CamelTestSupport test that shows the difference between exception from different calls. I would expect both tests to succeed and both methods to show the same exception behavior.

> When an exception is thrown from a transform method I lose the content of the message body. This behaviour is unexpected because it does not happen when an exception is thrown from a bean call.
> .bean(ErrorBean.class, ErrorBean.METHOD)
> Vs.
> .transform().method(ErrorBean.class, ErrorBean.METHOD)
> I have a testcase that I will try to get attached but here are the routes:
> {code:java}
> if ("testTransformExceptionToErrorRoute".equals(getTestMethodName())) {
>                     from(START)
