The error "*Database is already closed" *either could be a bug with carbon server shut down or calling forceful shutdown cased it. I did try to reproduce this issue with a latest CEP build and couldn't get the same error. However I have seen the same error with G-Reg while running integration test. So this issue is intermittent. Test framework calls forceful shut down after executing all tests. We hadn't use graceful server shut down as it was trend to keep the java process running without termination it (intermittently). BTW, are you getting this error constantly?
'*java.io.IOException: Stream closed" *is known issue with test framework and doesn't harm to test execution flow. I have create JIRA [1] to track it. Thanks, Krishantha.
