Eclipse 3.2RC1 (3.2.0 Build I20060413-1718), Sun 1.6.0-beta2-b77, Win XP SP2

On the same test case as [Bug 115918] :

==============================================
package bug;

public class BugBase<T extends BugBase> {
}
==============================================
package bug;

public class BugParent extends BugBase<BugChild> {
}
==============================================
package bug;

public class BugChild extends BugParent implements Comparable<BugChild> {

    public int compareTo(BugChild o) {
        return 0;
    }
}
==============================================


Pressing F3 key (open declaration) on "(BugParent extends)
BugBase" gives an "Error executing command" :

"Open Declaration" did not complete normally. Please see the log for more information.
Reason:
java.lang.NullPointerException

Selecting "Open declaration" in the contextual menu does nothing. It should go to the "BugBase" class.
