i am pretty sure i have the updated java though because when i run system updater it doesn't find anything to update, and that should be posted...
the exact message in the terminal was:
Last login: Fri Jan 9 00:27:02 on ttyp1
Welcome to Darwin!
Sarah-Minchoms-Computer:~ sarahminchom$ java -version
Bus error
Sarah-Minchoms-Computer:~ sarahminchom$
...it really just said bus error.
so is it that the java app is corrupt?
