Asynchronous File Poller has problems handling errors (likely regression introduced by SM-1441)

I have an integration process that begins with a smx-file poller endpoint and includes a smx-saxon component. In this flow, smx-saxon throws an exception which is reported back to the smx-file poller as an error. The SMX 3.2.2 file poller handles the error gracefully. The new SMX-3.3-SNAPSHOT file poller reports an error setting the exchange status to ERROR. This appears to be a regression due to SM-1441.

In order to reproduce the problem, first download and install apache-servicemix-3.3-20080927.213545-1.zip. Then replace the servicemix-saxon 3.3-SNAPSHOT version with the servicemix-saxon 3.2.2 version and update its jbi.xml to reference servicemix-shared-2008.01-SNAPSHOT. Only the servicemix-saxon 3.2.2 version throws the ClassCastException which exposes the smx-file problem. BTW, I have attached my test project in order for you to reproduce the problem.

The console log is reported below.
