ok, did that - would have been nice to use try-with-resources but I didn't
want to change too much and an operator's `close()` method does allow throwing
`Exception`s and so should `AbstractStreamOperatorTestHarness#close()`
(probably)

> Key: FLINK-6702
> URL: https://issues.apache.org/jira/browse/FLINK-6702
> Project: Flink
> Issue Type: Bug
> Components: CEP, Tests
> Affects Versions: 1.3.0
> Reporter: Nico Kruber
>
> During the CEP unit tests, when garbage collection kicks in and tries to
> finalize RocksDB, it may fail with
> {code}
> pure virtual method called
> terminate called without an active exception
> Process finished with exit code 134 (interrupted by signal 6: SIGABRT)
> {code}
> Reason is a missing {{harness.close()}} call in
> {{CEPOperatorTest#testCEPOperatorSerializationWRocksDB()}}.
