/**
* Test that deleting an employee works correctly.
* This test case was added in 8177 for 324321 and modified for 325605.
* The issue is that the status enum will be cascade deleted even if it is not
* instantiated (lazy) because the owning object does not know if the collection is empty
* without instantiating it.
* DB2 will therefore emit warning logs that are printed at FINEST in this lazy case.
* This test is a modification of testDeleteEmployee() that verifies instantiated lists are also ok
*
* 11/17/2010-2.2 Michael O'Brien
* - 325605: Filter out SQL warnings that are not SQL statements but are
* logged at a non-warning level. This affects only implementors of SessionLog that
* perform log diagnostics/tracking in addition to logging.
