>> Backporting JDK-8320687: sun.jvmstat.monitor.MonitoredHost.getMonitoredHost() throws unexpected exceptions when invoked concurrently. The fix proposes to guard the usage of the shared ServiceLoader instance through the monitoredHosts object monitor. Adds test. Ran GHA Sanity Checks, local Tier 1, 2, and 3, and new `test/jdk/sun/jvmstat/monitor/MonitoredVm/ConcurrentGetMonitoredHost.java` tests. Patch is almost clean (copyright header is slightly different).
