Update on this:  the new Derby passes tests, with the following impact:

1) It appears to be a little bit more memory-hungry, so it runs out of 
memory for some tests unless I add -Xmx128m to junit.jvmargs; I can do 
that permanently, which should also allow tests to run with Richard's 
memory limit changes enabled.

2) The nagging problem with 
VirtualCubeTest.testCalculatedMeasureAcrossCubes now shows up for every 
full run, even on my laptop.  Julian, I think you said you know what's 
going on with this--that it incorrectly computes the number of passes 
required in terms of the base cubes instead of the virtual cube, so the 
calculated measure will come out null if the cache wasn't primed?
