Hi all, The newly added test `test/hotspot/jtreg/serviceability/sa/TestJhsdbJstackPrintVMLocks.java` intermittent fails `the return value of "jdk.test.lib.apps.LingeredApp.getProcess()" is null`. This PR check `getProcess()` is null or not before invoke `destroyForcibly`. Test-fix only, the change has been verified locally, no risk.
