Eclipse QuickFix problem

Encountered a strange problem while working on Eclipse [In the latest integration build - Version: 3.1.0 Build id: 200412081200]

I wrote a small snippet of code -

    if(getContentSpec().equals("Test"))
        return true;

The method getContentSpec was not implemented in the class; so it gave a compilation error. I took the QuickFix route and asked Eclipse to generate the stub for me. To my surprise, it generated the following code -

/**
* @return
*/
private AbstractList getContentSpec() {
    // TODO Auto-generated method stub
    return null;
}

I didn't really expect the method to return a String - but I at least expected it to return an Object. But it ended by returning an AbstractList!!!!! This was s t r a n g e!

To recreate the problem, before I submit the bug, I created a simple class -

public class QuickFixEquals {

 	public boolean hasChildren() {
		
		return(getContentSpec().equals("Test"));
	}
}

Applied QuickFix ... and the code generated was

    private Object getContentSpec() {
        // TODO Auto-generated method stub
        return null;
    }

Well, thats what I wanted in the original code ... why did it behave differently here?

I finally tracked it down to ... guess what? ... an import statement.

Try QuickFix on the following code

import java.util.List;

 public class QuickFixEquals {

 	public boolean hasChildren() {
		
		return(getContentSpec().equals("Test"));
	}
}

It will generate

	private List getContentSpec() {
		// TODO Auto-generated method stub
		return null;
	}

Better yet, try this code

import java.util.ArrayList;
import java.util.List;

 public class QuickFixEquals {

     public boolean hasChildren() {
        return (getContentSpec().equals("Test"));
    }

     public List<String> getList() {
        return new ArrayList<String>();
    }
}

Apply QuickFix, and lo, you get -

    private AbstractList<E> getContentSpec() {
        // TODO Auto-generated method stub
        return null;
    }
