Build: N20050506-0010 1) I checked out org.eclipse.pde.* into my workspace 2) After it completed, I tried to open a type hierarchy on the class "Job". 3) I received a flood of error dialogs and > 200KB of error messages in my log file. From looking at the log, it looks like the initial problem is the PDE resource change listener throwing the NPE. However, this appears to cause damage to the JDT core state, possibly causing all the out of bounds exceptions. Logging against PDE, but there is likely a JDT problem here as well. I will attach the log file, but here is the top of each of the error stack traces. First stack: java.lang.NullPointerException at org.eclipse.pde.internal.core.WorkspaceModelManager$ModelChange.equals(WorkspaceModelManager.java:52) at java.util.ArrayList.indexOf(ArrayList.java:245) at java.util.ArrayList.contains(ArrayList.java:226) at org.eclipse.pde.internal.core.WorkspaceModelManager.handleFileDelta(WorkspaceModelManager.java:206) at org.eclipse.pde.internal.core.WorkspaceModelManager.visit(WorkspaceModelManager.java:477) Second stack: java.lang.ArrayIndexOutOfBoundsException: Array index out of range: 0 at org.eclipse.jdt.internal.core.util.BindingKeyParser.parseInnerType(BindingKeyParser.java:629) at org.eclipse.jdt.internal.core.util.BindingKeyParser.parse(BindingKeyParser.java:527) at org.eclipse.jdt.internal.core.util.BindingKeyParser.parse(BindingKeyParser.java:511) at org.eclipse.jdt.core.BindingKey.isParameterizedType(BindingKey.java:208)

I was able to easily reproduce this. It happens every time I open a type hierarchy on "Job" in my workspace. This happens even right after startup, in a session where the NPE from PDE did not occur. I'm going to move to JDT (although the PDE NPE is clearly also a bug).
The NPE in PDE is a dup of bug 91750. A method could potentially return null and we were not guarding against that.
