          Issue Type: Bug
            Reporter: Ranganath Chittari
            Priority: Blocker


Hello I am trying with application identity for my Entity.
I have String column in my class which acts as primary key. It has annotation:
@Persistent(primaryKey = "true")
When I try to persist this entity, it throws the following exception:
org.datanucleus.exceptions.NucleusException: The key value passed to construct 
a SingleFieldIdentity of type "javax.jdo.identity.StringIdentity" for class 
"com.wipro.wess.MOrganisation" is of an incorrect type 
("javax.jdo.identity.StringIdentity") - should be "String".

        at 
org.datanucleus.api.jdo.JDOPersistenceManager.getObjectById(JDOPersistenceManager.java:1740)

I tried to resolve it by extending javax.jdo.identity.StringIdentity class by 
overriding the method as below:
        public synchronized Object getKeyAsObject() {
                return (Object)this.orgId;
        }
But the same issue still persists. Please help me out on this issue

Thanks 
Ranganath
