NetBeans IDE Dev (Build 061004)

NPE is thrown when searching for method usages from base class [Object]

Steps to reproduce:
1) Have class:
public class TestClass {            
    @Override
    public String toString() {
        return super.toString();
    }        
}
2) put caret on declaration of method toString()
3) Find Usages - check Find Usages and Search from Base Class [Object]
-> java.lang.NullPointerException: Passed null to
FileOwnerQuery.getOwner(FileObject)
	at org.netbeans.api.project.FileOwnerQuery.getOwner(FileOwnerQuery.java:64)
	at
org.netbeans.modules.refactoring.classpath.RefactoringClassPathImplementation.getRelevantProjects(RefactoringClassPathImplementation.java:161)

Comment 2 Jan Becicka 2006-10-11 13:47:45 UTC 
I did some improvements:
Checking in RetoucheUtils.java;
/cvs/refactoring/java/src/org/netbeans/modules/refactoring/Attic/RetoucheUtils.java,v
 <--  RetoucheUtils.java
new revision: 1.1.2.2; previous revision: 1.1.2.1
done

I cannot reproduce this NPE, but I can reproduce different exception:

Comment 4 Tomas Zezula 2006-11-09 12:54:40 UTC 
After several already applied fixes I've got:
