Description
The PrintNMTStatistics flag doesn't work for normal JVM exit, works for Ctrl-C / sigint though. Turns out that print_memory_usage() is called but when trying to get the snapshot with get_snapshot() we return NULL since NMT is shutting down also. Attaching reproducer from Filipp Zhinkin who found this issue, repro with: java -XX:+UnlockDiagnosticVMOptions -XX:NativeMemoryTracking=detail -XX:+PrintNMTStatistics Test 5
