Description

Refactoring:

Class A exists
Create class B
Try to modify A by adding "extends B" --> Stack Overflow (also, on restart Eclipse complains about stack overflow)

The Eclipse log follows (there are lots of other errors before but they are separated from this one by a few minutes, so assuming unrelated).

Addition:

The problem may stem from this structure:

Base Class:

class DsMaps {
   ....
}

Derived class with inner Class:

class DsMapForSmartAttr extends DsMaps {

    public static class DsMaps {
    }

    public static DsMaps getX() {
       ....
    }
}

I have been trying to recreate the problem with some variant of the code that you have here. However, I cannot.

This stack trace is usually an indication of GRECLIPSE-531. Do you remember the steps that you took to get problem? This would help me reproduce.

Hi Andrew.

I'm sorry to say I cannot reproduce it. Everything works fine so far for things like

class A {

}

class B extends A {

    public static class A {
        // This is the class referenced by the the *extends*
        // Does that make sense?
    }

    public static A getA() {
        return new A()
    }
    
}

I recall that the error came up while I was really messily redesigning the class hierarchy. But that's about it.

Thanks for getting back to me. I will close this issue. But, please reopen and attach the entire stack trace if you ever see this happen again.
