  looks good.

Could you fix indentation of the assert texts so that the part within
the err_msg() call is aligned correctly? So instead of:

assert(someCondition,
       err_msg("....",
       arg1, arg2, ...));

use

assert(someCondition,
       err_msg("....",
               arg1, arg2, ....));


to make it more readable (in heapRegionRemSet.cpp, twice).

I do not need to see a re-review, but if jdk8u review guidelines tell
so, I will certainly look at these minor updates again.

Thanks,
  Thomas
