      Description

      Explicitly setting -XX:G1ConcRefinementThreads=0 disables all threads, while just keeping G1ConcRefinementThreads at its default value of 0 means to use the default number of threads.

      This is confusing.

      This behavior has been probably been introduced with JDK-8133051.
