[BUG] Java CI Workflow is flaky with JDK 11

Describe the bug
On JDK 11, sometimes the SQL Java CI workflow fails with the following error message from Github actions logs:

2022-03-01T22:54:17.7972264Z org.opensearch.sql.legacy.JdbcTestIT > testDateTimeInQuery FAILED
2022-03-01T22:54:17.8056027Z     java.lang.RuntimeException: org.opensearch.client.ResponseException: method [POST], host [http://127.0.0.1:32963/], URI [/_plugins/_sql?format=jdbc], status line [HTTP/1.1 500 Internal Server Error]

2022-03-01T22:54:17.8058336Z     }

Re-running the workflow can resolve the issue, but it should not fail in the first place. Running ./gradlew build locally on Mac with JDK 11 has no issues.
