Log Context

Log “thread allocated memory is not supported on this JDK”classname  is HotThreads.java We extracted the following from Elasticsearch source code for those seeking an in-depth context :

if (threadBean.isThreadCpuTimeSupported() == false) {
 throw new ElasticsearchException("thread CPU time is not supported on this JDK");
 } 
 if (type == ReportType.MEM && sunThreadInfo.isThreadAllocatedMemorySupported() == false) {
 throw new ElasticsearchException("thread allocated memory is not supported on this JDK");
 } 
 // Enabling thread contention monitoring is required for capturing JVM thread wait/blocked times. If we weren't
 // able to enable this functionality during bootstrap; we should not produce HotThreads reports.
 if (isThreadWaitBlockTimeMonitoringEnabled(threadBean) == false) {
