…Java streampark-flink-core was removed in apache#4432; migrate equivalent core infrastructure in streampark-flink-shims-base. Convert config, CLI, client traits, and env utils to Java while keeping Scala initializers/traits compiling against Java APIs. Closes apache#4446 (partial — 8/15 Scala files migrated) Co-authored-by: Cursor <cursoragent@cursor.com>
…tializers to Java Move SqlCommandParser, FlinkSqlExecutor, FlinkSqlValidator, and environment initializers from Scala to Java while keeping Scala trait bridges unchanged. Co-authored-by: Cursor <cursoragent@cursor.com>
…to-Java migration Convert FlinkStreamTableTrait, version-specific contexts/clients, and shims-test to Java; remove all remaining Scala sources under streampark-flink-shims. Co-authored-by: Cursor <cursoragent@cursor.com>
Add SonarCloud CPD exclusions for versioned shims modules, fix unused exception in FlinkTableInitializer, and simplify SqlCommandConverters quote stripping to satisfy reliability rules. Co-authored-by: Cursor <cursoragent@cursor.com>

SqlCommandCall.operands is now a nullary Java accessor; use operands()(n) instead of operands(n) to avoid passing the index to the method itself. Co-authored-by: Cursor <cursoragent@cursor.com>
