mailbox.log: java errors... anything to be worried about?

[jeg1972]

I've just been checking all of my logs in preparation for moving from 4.5.11 to 5.0.11, just make sure there aren't any real problems before the upgrade and I found many of these errors in the mailbox.log log file;

Now, I've used Tomcat in the past so I know these horrific errors don't neccessarily mean real bad things are happening... should I be worried?

I don't like bumping threads after only 24 hours, but I'm going to be upgrading my system tomorrow so I was just wondering if someone could have a quick look at the error messages above to see if I need to postpone the upgrade?

Thanks in advance!
