I’m trying to run my java application and I keep getting this error:

An internal error occurred during: “!DebugUITools.8!”.

I had a newer version of MyEclipse, but we have an older project and when I went to deploy it – it wouldn’t deploy correctly. The rest of my team had 3.7.101 on their machine therefore I had to change to what they had. But now that I did that this other project I’m working on keeps giving me the above error. I’m not able to run it as a java application. Does anyone have any ideas on what I need to do?

Ok – I have no idea what happened…..but I deleted one jar file from my project and magically it worked. I totally don’t understand what happened, but I’m glad it FINALLY works!! 🙂

Sometimes, I just smile, move on, and pretend I don’t really care what the cause was. 🙂
