java.util.ConcurrentModificationException [message #100094]

I created the project "Top down Web Services supporting flexible
projects." under "Web Services tutorials using WTP 1.0 M4 driver". I am
usign Eclipse 3.1.0 M6, WTP 1.0 M4, and Tomcat 5.0.28. I create the
project fine. I import the .wsdl file just fine. I create teh Web
Service by right clicking on the WSDL file and following the
instrucitons. Everything looks great. I can click on the Java or J2EE
perspectives and everything looks fine. However, when I close Eclipse and
re-open Eclipse I can the following error message when i try to open the
J2EE perspective (I saw a mention of this as a known issue but it was
supposed to be resolved with EMF I200504141117 build - the bundle that I
downloaded was newer than that build so it should have incorporated the
fix):

Unable to create view: An unexpected exception was thrown.

Interesting note:

If when I close Eclipse I switch to the Java perspective from the J2EE
perspective. When I open Eclipse again it will open the Java perspective
fine. I can also switch to the J2EE perspective without any error.

However, if I close Eclipse with the J2EE perspective open I still get
this same error message when I open Eclipse. I can switch to the Java
perspective without any message but when is switch back I still get this
same message.

This seems to be a bug.

TIA,
Ben
