Build 20021009 1. Create the following cu: public class X implements Missing { } 2. Open hierarchy on X Observe: The hierarchy is rooted at X. It should be rooted at java.lang.Object
Ok to fix.
Fixed HierarchyResolver.findSuperClass() to find the IGenericType of java.lang.Object if the source type's superclass is null. Added regression test TypeHierarchyTests.testMissingInterface()
I follow the step of the test case and "No Declaration of selected members in the chosen hierarchy of 'X'" appear in the Type Hierachy. The correct hierarchy is printed in Supertype Hierarchy. If you remove the 'implements Missing' in X.java there is an exception: !ENTRY org.eclipse.jdt.core 4 4 Oct 16, 2002 17:00:25.437 !MESSAGE Exception occurred in listener of Java element change

First problem was that the list of roots was empty (did not add java.lang.Object when there was a problem in the hierarchy). Second problem was in the data structure TypeVector that resized its internal array to an empty one. Fixed both cases.
Verified.
