Doesn't Apple control which Java is released? And any other can result in odd things. I'd head to Apple and ask how to clear up what you busted.

mac software update october 2012 suggested downloading oracle's java software which i did - version 7 update 9. my operating system is 10.7.5. now when i enter a chat room using java i cannot chat. while i may or not be able to type all words in the window (depends on chat room) when i go to enter the conversation nothing happens. there is no entry. for some reason the enter/return button does not work. i tried to uninstalled oracle java and reinstall mac's java but that proved unsuccessful. while the terminal window in utilities took the entry it deleted it as soon as i closed the window.
