CtFieldReference.getDefaultExpression() returns initializer from a field of another class

[bastik]

Hi, I'm trying to collect and evaluate certain strings in the source repository.

I tried VisitorPartialEvaluator, but it runs into an infinite loop. The reason of this is that fields get mixed up. The code setup is like this:

class BaseClass {
    public final static String PREFIX = "BasePrefix";
}

class ClassB {
    public final static String PREFIX = BaseClass.PREFIX + ".b";
    public String getKey() {
        return BaseClass.PREFIX + ".x";
    }
}

Now if you try to read the return value of the getKey() method, the CtFieldReference object will return the default value of ClassB.PREFIX, not BaseClass.PREFIX.

this bug is related to #756
I don't know how to resolve this bug without breaking #756

Or we have to introduce a method getCtField() in CtfieldAcess in order to know the target of the CtFieldAccess.
