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.
Tks,
Eric

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...
Thx for Reporting,

JPAStreamingMessage vs JPAMessage
---------------------------------
Key: IMAP-133
URL: https://issues.apache.org/jira/browse/IMAP-133
Project: JAMES Imap
Issue Type: Bug
Components: JPA Mailbox
Reporter: Tim-Christian Mundt
Priority: Blocker
With newest James I quite often (as always not always) get this error during
copy operations which causes them to fail:
Exception in thread "pool-8-thread-1" java.lang.ClassCastException:
org.apache.james.imap.jpa.mail.model.openjpa.JPAStreamingMessage cannot
be cast to org.apache.james.imap.jpa.mail.model.JPAMessage

streaming is set to false. I found the place where the JPAStreamingMessage
is created:
633 final MessageMapper<Id> mapper = createMessageMapper(session);
634
635 final List<MailboxMembership<Id>> originalRows =
mapper.findInMailbox(set);
in org.apache.james.imap.store.StoreMailbox. Those "originalRows" contain
the JPAStreamingMessage(s). The question here is: How does the mapper know,
which kind of Message to create - JPAStreamingMessage or JPAMessage? By the
way, the former is defined twice in persistence.xml. First I thought, this
might be the cause for the error, but really sometimes it gets the one type
and after restarting James it maybe gets the other (but always the same type
during one run).
