**Fixes #7297** ### Description This PR resolves the issue where running pipelines via the CLI (`hop-run.bat` / `hop-run.sh`) results in standard error (`stderr`) being flooded with `INFO` messages from the Microsoft SQL Server JDBC driver (`com.microsoft.sqlserver.jdbc.TDSTokenHandler`). Because the MSSQL driver utilizes standard `java.util.logging` (JUL), its default `ConsoleHandler` routes `INFO` level logs directly to `System.err`. This creates significant noise when users attempt to redirect real errors to dedicated log files (e.g., `2> error.log`). **What changed:** * Added a `silenceJulJdbcLoggers()` method call as the very first execution step in `HopRun.main()`, immediately preceding `HopEnvironment.init()`. * This sets the `com.microsoft.sqlserver.jdbc` JUL logger strictly to the `WARNING` level, effectively neutralizing the spam before any database driver classes are loaded. **Architectural Rationale:** While implementing the `jul-to-slf4j` bridge is a common workaround for JUL spam, it was intentionally avoided here. Apache Hop utilizes `slf4j-nop` (which discards SLF4J output natively) in favor of its custom `HopLogStore`. Additionally, the bridge is not a declared Maven dependency in the engine module. Directly targeting the noisy JUL logger level is a zero-dependency, surgical fix that avoids unnecessary abstraction overhead. ------------------------ Thank you for your contribution!
