I did further investigation on my unittest (code is pasted in my previous
email).
The second transaction block is not persisting the SecurityGroup Entity.
If I add the following line with in txn block,
securityGroup = pm.getObjectById(SecurityGroup.class,
securityGroup.getId());
I see the following in testresults file
Testcase: testSecurityGroupNotBelongToTenant took 0.239 sec
Caused an ERROR
The key value passed to construct a SingleFieldIdentity of type "class
javax.jdo.identity.StringIdentity" for class "class
com.veersoft.security.SecurityGroup" is null.
