I got a PM from the OP (Original Poster) asking for help with this thread. I'm not a Java expert by any means, but I'll help in any way that I can.
Based on what has been posted, it would appear that the Eclipse source files are corrupt. I'd try to download a fresh copy of the files, preferably from another mirror or source.
that can probably offer more expert advice than I can. There are Java coders that have lots more experience with Eclipse than I have on Hot Scripts.
