Most of these failures are because the exception message, in an exception that was raised, contains an unexpected value (apparently `null`). The test doesn't propagate the unexpected exception, thus it's not clear why the exception message is different than what the test expects. The commit in this PR propagates the original exception if the message is unexpected. This should help identify the underlying cause of the test failure, if/when it fails the next time.
