> OOZIE-1826 created {{JvmPauseMonitorService}} which uses Guava's stopwatch. 
> The implementation was heavily inspired by HADOOP-9618. Guava changed the 
> StopWatch class in a way that we either create a version which is compatible 
> in the old (Guava 11) or the new (Guava 27) interface. To make the code Guava 
> version independent we should not use this class anymore. Hadoop also 
> replaced this class in HADOOP-11032.
> We don't really need nanosecond accuracy here, we only read milliseconds from 
> the stopwatch and the default thresholds are 1 second 
> (oozie.service.JvmPauseMonitorService.info-threshold.ms = 1000ms) and 10 
> seconds (oozie.service.JvmPauseMonitorService.warn-threshold.ms = 10 000ms) 
> so even millisecond is a bit overkill. We could just use 
> {{System.currentTimeMillis()}}.
