GAE + GWT + roo-1.1.0.M3 fails

[opticrealm]

I've created a simple .roo script. When I run it with "mvn tomcat:run", everything is fine.

project --topLevelPackage org.pbjsoft.manbook --projectName manalive --java 6
persistence setup --provider DATANUCLEUS --database GOOGLE_APP_ENGINE 
entity --class ~.person
field string --fieldName name
field string --fieldName screenname
field string --fieldName aboutme
controller all --package ~.web
quit

When I type "gwt setup" in the roo shell, the application fails to start with either "mvn tomcat:run" or "mvn gwt:run".

In the terminal, I see these error messages when I run "mvn gwt:run":

In the GWT Development Mode window, I see this exception:

When I run it with "mvn tomcat:run" it now fails (since I typed 'gwt setup'). I get these errors in Terminal:

When I change the persistence provider to HIBERNATE on HYPERSONIC_IN_MEMORY, and run it with "mvn gwt:run", everything works.

persistence setup --database HYPERSONIC_IN_MEMORY --provider HIBERNATE

There seems to be a conflict when trying to use GAE with GWT with Roo M3. Have others experienced this? Is there a BUG ticket open? Is there a workaround?

In case this matters:

I'm on Ubuntu 10.10.

pakelley@Minitacular:~$ uname -a
Linux Minitacular 2.6.35-22-generic #34-Ubuntu SMP Sun Oct 10 09:24:00 UTC 2010 i686 GNU/Linux

Same problem. About to give up on roo with GAE.
