@TheNeuralBit For some reason "Flink CrossLanguageValidatesRunner Tests"
timeouts on xlang_jdbc test and on the other hand the same test passes on
Python precommit suite.
At first it didn't see the URN as it wasn't added to the test expansion
service. But now I have no idea what's going on, everything seems to be like in
generate_sequence but for some reason my test gets hanged forever.
I changed the test to use EXPANSION_PORT when available because Postcommit
suites run test expansion service and expects the tests to use it.
Do you have any idea what could be the reason or how to debug it?
I managed to run the scripts
```
run_job_server.sh ...
run_expansion_services.sh ...
./scripts/run_integration_test.sh --pipeline_opts "--runner=PortableRunner
--environment_cache_millis=10000 --job_endpoint=localhost:18091" --test_opts
"--attr=UsesCrossLanguageTransforms" --suite xlangValidateRunner
```
Tests fail with output:
```
-------------------- >> begin captured stdout << ---------------------

--------------------- >> end captured stdout << ----------------------
<_InactiveRpcError of RPC that terminated with:

```
Could it be that Postgres container is running in another container?
