Subject svn commit: r495364 - /db/derby/code/trunk/java/testing/org/apache/derbyTesting/functionTests/tests/jdbcapi/AutoloadTest.java

New Revision: 495364

URL: http://svn.apache.org/viewvc?view=rev&rev=495364
Log:
DERBY-1952 (partial) Copy & refactor AutoloadTest as jdbcapi.AutoloadTest as it
can be used on non-JDBC 4 environments as long as it is not compiled using Java SE 6.
Split into a number of test cases including one to ensure the junit setup is not
autoloading the test (thus potentially hiding real issues) when autoloading is
not enabled. Test runs successfully without the old harness but not yet added
to any ant target as it needs to set the property jdbc.drivers for effective testing.
The jdbc4 version is not removed until this version is running as part of
the ant targets.
