What is this PR for?
In
Notebook.recoverRunningParagraphs(), theInterruptedExceptioncaught fromthread.join()was handled withe.printStackTrace(), which bypasses the project's Log4j2 configuration. Additionally, the thread interrupt status was not restored, preventing callers from observing the interruption. This PR replacese.printStackTrace()with SLF4J logging and addsThread.currentThread().interrupt()to restore the interrupt status.What type of PR is it?
