Created attachment 127444 [details] Error log I have a rather extensive class hierarchy with and interface at the top, an abstract class that implements it and then many more abstract and concrete classes that extend those. Ex. A (interface) - B (abstract class) - C (abstract) - D (concrete) - etc. I can view the type hierarchy from C and everything below it, but as soon as I try to view the type hierarchy of either A or B I get an exception. The error log shows the following (I also attached the file) : eclipse.buildId=M20080911-1700 java.version=1.6.0_10-rc java.vendor=Sun Microsystems Inc.

A reproducable test case would be welcome.
(In reply to comment #1) > A reproducable test case would be welcome. > Hi. Thank you for the quick reply. It is only in this specific type hierarchy that I experience this problem. It works for all other type hierarchies, which means I can't reproduce it for anything other than this one, but unfortunately I cannot distribute the source code I'm working with. If it will help, I can write out the type hierarchy for you. Also, part of the stack trace I sent you contains an entry that may help : Root exception: java.lang.NullPointerException at org.eclipse.jdt.internal.compiler.lookup.TypeBinding.findSuperTypeOriginatingFrom(TypeBinding.java:301)
If you could, please try your workspace with a recent 3.5 integration build, so we will know if this case has been fixed since 3.4.1 Also could you please attach your type hierarchy with ALL type variables. Are there any member types or anonymous types in the hierarchy ? thanks
Waiting for more information Please see comment #3
