Investigation and Optimization of Long GC Pauses Caused by Excessive FinalReference in Spring Cloud Gateway

The team discovered that frequent Logback file rotations created thousands of FileOutputStream objects whose finalize‑based FinalReference instances flooded the G1GC reference‑processing phase, causing 13‑second pauses, and resolved the issue by enabling parallel reference processing, enlarging log rotation size, and adjusting GC initiation thresholds.
