Michael Bouschen commented on JDO-580:
--------------------------------------
Thanks for catching this, Andy.
Yes, the expected result should be Integer instead of Long, since the size
methods returns an int.
I fixed the testcase and checked in the fix (see revision 958269).
> Add TCK query test using methods in the query result

> There are currently no TCK tests for using size() and max() or other
> aggregates in queries. For example, find the Node or Nodes with the maximum

> MAX(n.children.size()) FROM Node n).
