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

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

Hi,
I think you're using a version of AJDT (1.1.12 perhaps?) which is not
supported on Eclipse 3.1M4. Fortunately there is a version available for
this Eclipse build, although it is a development build. It is available
via the AJDT download page:
http://www.eclipse.org/ajdt/download.html
Look for the 1.2.0.DEVELOPMENT builds section, the current one is
1.2.0.20050202134544. Note there are two of these builds, one for Eclipse
3.0 and one for 3.1M4, so please make sure you get the right one.
Regards,
Matt.
