CallingJdoPreclear tries to add the same instance to multiple 1-M relations
---------------------------------------------------------------------------

                 Key: JDO-414
                 URL: http://issues.apache.org/jira/browse/JDO-414
             Project: JDO
          Issue Type: Bug
          Components: tck20
    Affects Versions: JDO 2 final
            Reporter: Marc Prud'hommeaux
            Priority: Minor


The CallingJdoPreclear test tries to add the same instance to multiple one-to-many relations
in different instances, which may result in validation errors at commit time. The code that
does this is:

        primaryObj.addChild(secondaryObj);  // primaryObj contains one child;  secondaryObj
contains none. primaryObj is now dirty
        ... 
        ternaryObj.addChild(secondaryObj);

Errors can be worked around by removing secondaryObj from primaryObj.children before adding
it to ternaryObj. E.g.:

        primaryObj.addChild(secondaryObj);  // primaryObj contains one child;  secondaryObj
contains none. primaryObj is now dirty
        primaryObj.children.remove(secondaryObj);

        ...
        ternaryObj.addChild(secondaryObj);

Alternately, the call to "primaryObj.addChild(secondaryObj);" can probably just be skipped
... it doesn't look like it would impact the test case.
