 This test should normally be run before the generic tests

 so that the generic tests will actually test them. Otherwise,
 when the generic tests are run, they won't see any instances
 of many of the AMXConfig MBeans.
 <p/>
 If there are errors doing this, disable this test in amxtest.classes,
 fix the error in the specific place it's occurring, then re-enabled
 this test.
