Review Comment:
   There was a community discussion on trying to avoid timeouts (see 
[discussion 
thread](https://lists.apache.org/thread/q11t0y3qsw07lkb811037h4mvx0r7ncn) and 
[corresponding Flink coding 
guidelines](https://flink.apache.org/contributing/code-style-and-quality-common.html#avoid-timeouts-in-junit-tests)).
   The decision was only made on unit tests but I don't see why the same 
wouldn't also apply for integration tests. WDYT?

Review Comment:
   ```suggestion
                               return actualConfig != 
serializableConfigUnderTest
   ```
   nit: I'd prefer keeping it in the test method's context as much as possible.
