I think the test failure comes from this code running after this test had finished running.
You need to add testRunner.waitUntilDone where you call dumpAsText,
and call testRunner.notifyDone when the test is done running perhaps at the end of dooutdent?
Be sure to verify that the crash still reproduces without the fix if you made those changes to the test.
