Subject [jira] Commented: (JAMES-419) NPE during 8bit conversion of non-mime messages
Date Wed, 22 Feb 2006 21:01:38 GMT
    [ http://issues.apache.org/jira/browse/JAMES-419?page=comments#action_12367412 ] 

Stefano Bagnara commented on JAMES-419:
---------------------------------------

Javamail 1.3.2 SMTPTransport@702:
"if (enc.equalsIgnoreCase("quoted-printable") ||"
Probably you're trying to send a message with no encoding. Btw It should not throw an NPE!

Please post here the message your are trying to send so we can debug the problem.

Thank you for reporting it. 
---------------------------------------

Unfortunately generic exceptions in the delivery process ends in message purging:

} catch (Exception e) {
// Prevent unexpected exceptions from causing looping by removing
// message from outgoing.
// DO NOT CHNANGE THIS to catch Error!  For example, if there were an OutOfMemory condition
// caused because something else in the server was abusing memory, we would not want to
// start purging the outgoing spool!
outgoing.remove(key);
throw e;
}
} catch (Throwable e) {
if (!destroyed) log("Exception caught in RemoteDelivery.run()", e);
}

Is not so easy: read the comment of the catch.

Eg: Now the NPE is a bug in javamail, but we can't know what to do: if the NPE was from the
"store" of the repository then storing the message in the error-processor would end in an
infinite loop.

We probably should change our behaviour only when the exception is caused by the "delivery"
call.

I'll try to put in this improvement for 2.3.0a2. But I would also like to find out the NPE
problem while working on that code.
