On a slightly different note also be aware that quite a few Java exploits are going around in the wild, some from legit websites, blogs, etc.
I know there are a lot of Java based apps out there but if you don`t really use/need it, is it worth having it installed seen as the bad guys seem to be targeting it more often (plus Sun/Oracle`s dire security patching)
At the very least if your a 32Bit user you could use sandboxie thus mitigating the risk.
Some debate here
