OGT throws NPE when serializing objects of type java.lang.Object.

[tzaeschke]

Storing an instance of the following class would throw an NPE in the ObjectGraphtraverser:

class PureObject extends PersistenceCapableImpl {
    private Object o = new Object();

    protected PureObject() {
        // no-argument constructor for zoodb.
    }

    public Object getO() {
        return o;
    }
}

A unit test is available in Test_084_SerailizationBugRefToPM.testSerializationPureObject().
