James trunk on java6 runtime
Hi all,
I'm running a build of svn trunk on java6 and I'm experiencing some
security related errors.
My colleague running james 2.2 on java 6 is also experiencing security
related issues with the same Exceptions.
in the pop3serevr log I get:

This looks like it could be a problem associated with a move from
java5 to java6, but I'm not sure how to fix it.
Any help from you guys would be appreciated.
Thanks,
Kev

Hi Kevin,
Unfortunately we didn't test Java 6, yet.
Please file a JIRA issue for this so we can track informations and
remember this.
I ran a search for "Could not generate dummy secret" and
"SunTlsRsaPremasterSecret" on google with no results. Maybe in a few
weeks we'll find someone else reporting similar problems and explaining
us what is happening and how to fix it.
