Hey Robert, please correct me if I am wrong. According to this doc,
https://docs.oracle.com/javase/7/docs/jre/api/management/extension/com/sun/management/OperatingSystemMXBean.html
OperatingSystemMXBean of the sun package is available for Java 6 too. Only the method
getProcessCpuTime is unavailable. Hence I believe the logging and exception will not occur
for each heartbeat.
> Improve TM Monitoring: CPU utilization, hide graphs by default and show summary only
