I'm seeing this error too. I haven't studied the details, but I think JaCoCo gets confused by the upgrade tests using multiple versions of derby.jar. Notice that the stack trace contains classes like Driver169, which aren't on trunk, so it looks like the exception happens when the test is running an old version of Derby. There may be a way to configure the test runs so that JaCoCo doesn't get confused by the many versions of derby.jar, but I'm afraid I'm not that familiar with JaCoCo yet. In my run, the error doesn't make the test run fail. It only gets printed to the console. The tests seem to be able to continue, and the coverage report looks reasonable. -- Knut Anders
