I got the same message yesterday after installing the latest Java update (1.7.45) and then firing up OpsManager (yes, I'm still using it for a very very large customer). Backing down Java at least a release or 2 should get rid of it, but I'm concerned that a future Java update is going to cause me a lot of headaches. Used to be you could have multiple older versions running and the PC would use whatever release was required by the application, but that seems to no longer be the case.
