[jira] [Commented] (CAMEL-4449) NullPointerException when
unmarshalling using serialization data format
Posted by "Mathieu Lalonde (JIRA)" <ji...@apache.org>.

Mathieu Lalonde commented on CAMEL-4449:
----------------------------------------
XStream can serialize classes even if they don't implement Serializable. Did the the class for you message body implement Serializable? If not, then it was suppose to fail so the resolution might just be to give a more descriptive error message and perhaps a more meaningful exception?!
