Build Identifier: I20110613-1736

Trying to change syntax coloring for several items it occurs error - An internal error occurred during: "Semantic Highlighting Job". It happens for items: Classes, Constants, Deprecated members, etc. But for Number, Keyword, String, for example, no errors.  Example window that is shown bellow items reflects all changes correctly. But the editor doesn't.

Here is exception trace:

java.lang.StackOverflowError 
at org.eclipse.dltk.internal.core.ProjectFragment.hashCode(ProjectFragment.java:114)
at org.eclipse.dltk.internal.core.ScriptFolder.hashCode(ScriptFolder.java:127)
at org.eclipse.dltk.internal.core.ModelElement.hashCode(ModelElement.java:299)

at org.eclipse.dltk.internal.core.hierarchy.TypeHierarchy.getSuperclass(TypeHierarchy.java:589)
at org.eclipse.dltk.internal.core.hierarchy.TypeHierarchy.getAllSuperclasses(TypeHierarchy.java:483)

... the same as the last exception. It seems like non-end loop.

There is installed Java 7 (build 1.7.0-b147)

Reproducible: Always

Steps to Reproduce:
1. Window > Preferences > PHP > Editor > Syntax Coloring
2. Change color for Classes
3. Apply

I've tested my project at Linux (x86-64)
Build ID - 20110615-0604
PDT Build ID - 3.0.0 v20110516-1100
Works without any problem

This issue has the same cause as described in Bug 355312.
There no errors if syntax coloring is changed while all project files are closed.
