That seems to back up what I said to you earlier, pm. Since LW runs on Java. If Java is failing, then naturally LW will follow it if gets that far. Dare I say it & Stief may disagree here, but a clean re-install may be in need. I didn't dare suggest this 2 days ago although I thought it. I suspect there's something wrong with your Java installation. When installing/updating try to refrain from using other apps - I know how tempting it can be. But wait on Stief's response 1st! I'm no OSX expert!
