I just moved up from 3.1M3 to 3.1M4. I'm getting frequent Error dialogs,
usually when I go to open a project or package but occasionally when I just
access a file. In the log the error is always the same:
java.lang.ClassCastException: java.util.ArrayList
at
org.eclipse.ajdt.buildconfigurator.PropertyPageManager.extra ctJDTRegistryPag
eContributors(PropertyPageManager.java:120)
Modulo these dialogs everything seems to work. I spent the last 45 minutes
searching the newsgroups but I didn't see a reference to this problem. In
case it's brand new here's the log file header information:

I've got some code that requires Java 5 so I'd like to stay on M4 but those
dialogs are getting really annoying.
Thanks ... WkH
