[Failing Test]: beam_PreCommit_Java_GCP_IO_Direct high possibility timeout

### What happened?

When not timing out, the test takes ~30-40 min; or it timing out after 2 hour: https://ci-beam.apache.org/job/beam_PreCommit_Java_GCP_IO_Direct_Cron/

From the log, in the cases of timeout, the task gets stuck early:
```
17:53:23 > Task :sdks:java:io:google-cloud-platform:expansion-service:distZip
17:53:48 > Task :sdks:java:io:google-cloud-platform:test
17:53:53 > Task :sdks:java:io:google-cloud-platform:expansion-service:shadowJar
17:54:03 > Task :sdks:java:io:google-cloud-platform:expansion-service:startShadowScripts

17:54:11 > Task :sdks:java:io:google-cloud-platform:expansion-service:check
17:54:11 > Task :sdks:java:io:google-cloud-platform:expansion-service:build
19:52:33 Build timed out (after 120 minutes). Marking the build as aborted.
```
Particularly, `:sdks:java:io:google-cloud-platform:test` is executing but `:sdks:java:io:google-cloud-platform:integrationTest` not yet started. Likely some unit test having race conditions.

Start with the ci-beam.apache.org beam_PreCommit_Java_GCP_IO_Direct_Cron job and compare logs where :sdks:java:io:google-cloud-platform:test stalls before integrationTest starts. Inspect the Java Google Cloud Platform test task and identify the flaky unit-test behavior; done means the job completes reliably within its timeout.
