    Description

      JDK-8228818 introduced two new root-specific counters:
       https://hg.openjdk.java.net/jdk/jdk/rev/ddc79542ce3a#l10.14

      ...but there is no relevant roots block in the counter table. Therefore, while guarantee is there to check that we are safe to add the merge the bunch of counters into the counters table, we actually overwrite the subsequent, unrelated counters.

      We need to introduce the proper roots blocks for those affected counters.
