Thanks for the prompt response, Staffan!
One question is re support of existing flags (in particular GC flags) and

existing jmap interface. I am sure that will be detailed in the JEP in
In the much shorter term, I was wondering if the step of changing the
GC-logging flags could be accomplished, since that would really involve a
quick audit and some
really quick performance numbers to ascertain that something unexpected did
so should be relatively lightweight....
