Move test cases, test objects and mappings into subdirectories (e.g. jdo.tx0x for tests TC01, TC02 ...). Tests with lots of classes involved will get their own subdirectory. Also test numbers will change and the current grouping will be dropped as it did not fit also in the past.
The old logging stream will also be replaced with commons-logging.
I'll intend a second refactoring that will enable running tests from ant or within eclipse. A third refactoring should target to execute the sql scripts throughCTF-JDO test framework like: 'test -setup castor.mysql'. That will allow to put also the scripts into the subdirectories.
