On a related issue regarding Serializable that occured to me: We recently made a Wicket GUI interface for traced routes using org.apache.camel.processor.interceptor.jpa.JpaTraceEventMessage do store event messages.
We wanted to use this class directly in dao methods, for searching, listing and displaying in Wicket but as it's not Serializable we had to make our own version of the class to make Wicket really really happy. That would help when sending the jpa event message through jms, towards a jpa endpoint as well. Couldn't you at least make this class Serializable as it only contains Strings and Date anyway?
