Description

Current the JvmPauseMonitor.SLEEP_TIME is hard coded to 500ms and the default value of sleepDeviationThreshold is 300ms. In this case, JvmPauseMonitor may not be able to detect an extra sleep violating the threshold. Consider the following:

1. JvmPauseMonitor sleeps at T
2. A pause start at T+50ms and ends as T+400ms, i.e. the pause is 350ms
3. JvmPauseMonitor wakes up at T+500MS and detects no extra sleep.
