The state of the Thread Contention Monitoring feature. This feature can be: unsupported: The JVM does not support Thread Contention Monitoring. enabled : The JVM supports Thread Contention Monitoring, and it is enabled. disabled : The JVM supports Thread Contention Monitoring, and it is disabled. Only enabled(3) and disabled(4) may be supplied as values to a SET request. unsupported(1) can only be set internally by the agent. When the feature is unsupported(1), any attempt to change that value will fail: trying to set this object to enabled(3) or disabled(4) will result in an `inconsistentValue' error. Trying to set it to any other value will result in an `wrongValue' error.
