During JDK-8334305 cleanup, a host of deprecated methods were encountered. It is difficult to maintain the library code when we have legacy usages.
This enhancement would act as an umbrella bug to remove the following deprecated methods of nsk.share.Log,
empty constructor Log()
println
comment
logTo

Dividing the code change into sub-tasks would help isolate any issue that might arise during the fix although we would lose out in some common testing effort.
