Release locks between junit tests

Release locks between junit tests

Tdjam junits were randomly failing.  Traced it down to the fact that the
locks were being released asynchronously and thus were not always
released when the next test cases requested them.
Also simplified logging for tdjam junit tests.
Fixed the property file so it isn't overwritten by the junit tests.

Changes per review comments:
- changed "Pattern" to "pattern" in logback xml
