Don't worry, it is just a sign you should give up on Azureus and go with uTorrent instead. The main reason being that uTorrent doesnt need Java, is a smaller installation that takes less resources.
The downside of uTorrent is the lack of a blue frog logotype. Serious flaw, granted, but I believe you will still be ok.
As far as I know uTorrent also supports UPnP so why not give it a go?
