Kathey Marsden commented on DERBY-3819:
---------------------------------------

I wonder if it would work/be appropriate to import ClassSize and have something like:
 if (ClassSize.getRefSize() > 4)
            systemProperties.setProperty("derby.language.maxMemoryPerTable", "2048");

That way we would be sure we are using the same caclulations as the engine to determine whether we bump the memory.

Thoughts?
