The other day I had an issue with Mac OS, not sure what, but long story short I reinstalled/downgraded to Leopard. I have since installed all the Software Updates and such, but have not upgraded to Snow Leopard. (I'd had alot of issues with it, figured I'd stay downgraded for awhile)
In any case, I was able to download and run Java files no problem on Snow Leopard, but no longer can. It's not a ONE Java file problem, I've tried more than one and they all give the same message:
And if I check what it says, this is all that's there:
Well, I copied what appeared at the time. That launchd stuff is happening continuously, dunno if it's related. But yes, it says there's an exception in main and such...never got such errors running the exact same java programs on Snow Leopard.
Any thoughts?
