In v3.1.1 the test case class name in the output for ut_junit_reporter is empty:
Output is as follows, i.e.:
<testsuites ..><testsuite ..><testcase classname="" .. >

Test is run via SQL console with ut.run(':suite.testpackage', ut_junit_reporter());

In comparison to v.3.0.4 this seems not to work as expected anymore, or is something missing in the "run" configuration?
