      Description

      The following events were added in JDK 9

      G1MMU
      G1BasicIHOP
      G1AdaptiveIHOP

      but they have incorrect metadata and lack proper units. For instance, G1AdaptiveIHOP#predictedAllocationRate uses DOUBLE instead of a proper time unit, like TICKSPAN.The field names and labels could also been improved.

      It's important these events are fixed in JDK 9 to avoid compatibility problems in later releases.
