/**
* This test suite is for trac items where the failure mode is a 500 error caused
* by a software error, often in the static optimizer.
*
* The tests each consist of a test query in a file in this package.
* The typical test succeeds if the optimizers run on this query without a disaster.
* This test suite does NOT have either of the following objectives:
* - that the static optimizer is correct in the sense that the optimized query has the same meaning as the original query
* or
* - an optimizer in the sense that the optimized query is likely to be faster than the original query.
*
* The very limited goal is that no uncaught exceptions are thrown!
