      Description

      Beginning with JDK-8038423 there is more to do during heap sizing. Not only the Java heap is committed, but also all additional auxiliary data structures as needed.

      This increases heap size changes duration significantly, that is currently only recorded in the "Other" time.

      Add a measurement probe for heap expansion to the "Other" category.
