Re: [jira] Created: (IMAP-133) JPAStreamingMessage vs JPAMessage
As a quick workaround , you should just remove the *Streaming* stuff from the persistence.xml file. It seems like the classloader gets confused otherwise sometimes...

Re: [jira] Created: (IMAP-133) JPAStreamingMessage vs JPAMessage
Hi Tim-Christian, I stopped james 2 days ago for small config change (btw hot-config would be great :)) and I received exactly the same exception (I already saw it once or twice). The exception was shown only when fetching mails on one specific account. I deployed a fresh version of james trunk, and by magic, the error had disappeared . I will report if I still encounter the exception.
