### What changes were proposed in this PR? - Delete `MySQLSourceOpExec` and `MySQLConnUtil`, the executor and JDBC connection helper for the deprecated MySQL source operator, which have been unreachable dead code since the `mysql-connector-java` driver was dropped in #4386. - Reduce `MySQLSourceOpDesc` to a deserialization-only stub: `getPhysicalOp` now throws `UnsupportedOperationException` instead of wiring the deleted executor, and the `MySQLConnUtil`-based `establishConn` override is removed, while its fields, `operatorInfo`, and `updatePort` remain so legacy workflows still deserialize. - Add a comment at the `LogicalOp` type registration noting the type is retained non-executable for legacy-workflow deserialization only. - Update `MySQLSourceOpDescSpec` (flip the `getPhysicalOp` case to assert it throws, keep the deserialization coverage) and delete `MySQLConnUtilSpec` along with the util it covered. ### Any related issues, documentation, discussions? Closes: #6051 ### How was this PR tested? - Run `sbt "WorkflowOperator/testOnly *MySQLSourceOpDescSpec"` and expect 5 tests passing, including the flipped case asserting `getPhysicalOp` throws `UnsupportedOperationException` and the round-trip test confirming a `MySQLSource` node still deserializes into a `MySQLSourceOpDesc`. - Note: tests were run locally under JDK 17; under JDK 25 the sbt-jacoco 0.8.11 instrumentation step fails on a dependency class before any test runs, which is an environment/tooling limitation unrelated to this change. ### Was this PR authored or co-authored using generative AI tooling?
