Runtime instance error after upgrading to Juno + xtext 2.3 [message #904121]

Upgraded my (previously working) project to juno + xtext 2.3 from helios/2.1. When I try to start a runtime instance I get the exception below. Any suggestions for rectifying appreciated.

Also any other pointers/gotchas for upgrading?

Thanks.

Fixed. Clean build, re-launch after adding the following vm args back in to run config did it:

-XX:MaxPermSize=128m
-Xmx512m
