[jira] [Created] (SPARK-52126) Revert rename for TWS utility classes for forward compatibility in Spark Connect

------------------------------------

             Summary: Revert rename for TWS utility classes for forward compatibility in Spark Connect
                 Key: SPARK-52126
                 URL: https://issues.apache.org/jira/browse/SPARK-52126
             Project: Spark
          Issue Type: Bug
          Components: Connect, Structured Streaming
    Affects Versions: 4.1.0
            Reporter: Jungtaek Lim


We just figured out the refactor of some classes when we performed in SPARK-51814 broke "forward compatibility" for Spark 4.0 client vs Spark 4.1 server in Spark Connect.

This wasn't caught since we are yet to release Spark 4.0 hence we don't have automatic test with it in OSS.

Reverting the refactor would be the simplest way to fix the issue.
