Hi all,

  can I have reviews for the following small change that fixes incorrect
reload of the original value of a CAS target in
Bitmap::par_put_range_within_word?

Contributed by Matthias Braun from SAP.

(Which means we have a the review stamp from me already).

There seem to be more of these issues in the GC code, a first attempt to
catch them is recorded in JDK-8033552.

CR:
https://bugs.openjdk.java.net/browse/JDK-8033545

Webrev:

Testing:
jprt

Thanks,
  Thoams
