How would you investigate unusually long GC pauses, including pauses that grow after a new release?
Tests whether you'd pull GC logs (-Xlog:gc*) to check for full GCs vs young-gen collections, correlate pause growth with a recent change in allocation rate or object retention, and consider whether the collector (G1 vs ZGC) matches the new workload's latency profile.
