Versions for a Datanucleus + MVC + HSQL project

I've created the following roo project within datanucleus

// Spring Roo 1.2.1.RELEASE [rev 6eae723] log opened at 2012-03-21 22:27:38
project com.dn --java 6
//persistence setup --provider HIBERNATE --database HYPERSONIC_IN_MEMORY
persistence setup --provider DATANUCLEUS --database HYPERSONIC_IN_MEMORY
entity jpa --class ~.shared.domain.Contact
field string --fieldName fullName --notNull
field string --fieldName email
field string --fieldName phoneNumber
logging setup --level DEBUG
web mvc setup
web mvc all --package ~.server.web
web mvc finder all
exit

//Fails trying to compile with command shell
mvn clean install

a conflict with datanucleus-core-3.1.0-m2 version. I've tried to add runtime for the -core dependency :
<groupId>org.datanucleus</groupId>
<artifactId>datanucleus-core</artifactId>
<version>3.0.7</version>
<scope>runtime</scope>
or change the version to a range
<groupId>org.datanucleus</groupId>
<artifactId>datanucleus-core</artifactId>
<version>[3.0, 3.1)</version>

and I could compile successfully,
but when I try to run the project, it fails in both cases
mvn jetty:run
...Caused by:

cacion que utilisas?) : javax/jdo/JDONullIdentityException

.java:108)...

I've tryed Spring Roo 1.3.0.BUILD-SNAPSHOT [rev 47ce1ea with same results. This version contains an update of version (3.0.8 instead of 3.0.7 of the ROO 1.2.1)

No issues within HIBERNATE (instead of DATANUCLEUS)
I showed 1.2.1.Release includes an update to datanucleus-appengine 2. Is it really working?
What are the right versions to be used?
