    Description

      If you run the aggregate recommendation algorithm with a value of rowCountEstimate that is wrong and large, the algorithm runs for a long time and eventually fails with "OutOfMemoryError: GC overhead limit exceeded".

      I have added LatticeTest.testLatticeWithBadRowCountEstimate as a test case.
