Hi,

I am new to the forums and I have searched to no end regarding an issue I am encountering every time I open an ant file in Eclipse or Flash Builder.

For reasons I cannot figure out, when I open an ant xml file, I get an error that says "Could not open the editor: An unexpected exception was thrown." What is strange is it is happening more and more often and it only requires opening the file. I have read online about this possibly being related to the folding of Ant files. Unfortunately, this solution hasn't helped.

Here are the details of the error.

Would someone please provide some insight on why this is happening? It would be much appreciated.

Thanks,
