> Notice that it's junit that's running out of memory - it's unable to handle
> the huge amount of dfo test logs that are being output at debug level due to
> this in the test:
> @Before
> public void setDebug() {
> Logger.getRootLogger().setLevel(Level.DEBUG);
> }
> The test should not set the debugging level, rather this should be set in the
> log4j.properties file. Such code should be removed from all tests.
