ClassCastException most likely when edit java with generics

I was unable to reproduce. Could you, please, provide the source, where it occured?

We no longer need the source and steps, we are able to reproduce.

The CCE happens if you have class like this: 
public class NewClass<E> {
    <T extends E> void hhhh(T x) {   
    }
}

This class must be read from classfile (this happen when source is to available). Important think is that 
type parameter T must extends another type parameter.

There is easy way how to reproduce this CCE in a different scenario. 
1) Add above class to j2se project.
2) complie this class
3) go to Files Tab and in build firectory find the class file corresponding to the NewClass.
4) still in the Files Tab expand NewClass node.
5) CCE is here. :-)

We already have trivial fix, which will go to release50 branch.

Fixed in trunk.
