N20050505 I opened a type hierarchy on org.eclipse.core.expressions.Expressions and got an error dialog with a corresponding exception in the log. java.lang.ArrayIndexOutOfBoundsException: 0 at

I cannot reproduce this problem. Do you have more details on the projects that are in your workspace (source vs binary, version number if checked out from CVS, etc...) ?
I can't reproduce this in N20050506.
Oops, I can reproduce. The hierarchy was on org.eclipse.core.expressions.Expression - *NOT* Expression*s* as originally indicated. I have the following plugins in source, checked out from HEAD. org.eclipse.jdt.doc.isv org.eclipse.platform-feature org.eclipse.releng org.eclipse.test.performance.win32 platform-ant-home platform-debug-home org.apache.ant org.eclipse.ant.core org.eclipse.ant.tests.core org.eclipse.ant.tests.ui org.eclipse.ant.ui org.eclipse.core.variables org.eclipse.debug.core org.eclipse.debug.ui org.eclipse.jdt.debug org.eclipse.jdt.debug.tests org.eclipse.jdt.debug.ui org.eclipse.jdt.launching org.eclipse.jdt.ui.examples.javafamily org.eclipse.platform.doc.isv org.eclipse.test.performance org.eclipse.ui.console org.eclipse.ui.externaltools
I made the same exception occurr twice, but it does not happen everytime. Not sure what the requirements are. However, while attempting to cause it to happen I ended up with what seems like a deadlock. I restarted my workbench with the hierachy for Expression open, which showed a background job restoring the type hierachy for Expression. I pressed "cancel" (in the progress view) and tried to open another type hierarchy on a different class. The UI seemed to block forever with a busy cursor. Had to kill Eclispe. I will attach the thread dump.

*** Bug 93995 has been marked as a duplicate of this bug. ***
Thanks Darin. Fixed IndexBasedHierarchyBuilder#searchAllPossibleSubTypes(...) to use the characters between the last $ and the ".class" as the type name for a local or anonymous type (and not an empty name as it used to be). Added regression test TypeHierarchyTests#testAnonymousType7().
Verified for 3.1 M7 using build I20050509-2010 + jdt.core HEAD.
