Hi Sergey,
I've updated the PR with the map max size thing and sent you 2 jfr recordings
from some basic test I ran locally.
Please let me know what you think.

> MediaTypeHeaderProvider.valueOf(String mType) ends up being called a lot with
> the same parameter values, as those are basically the contents of the
> @Produce annotations on resources. Each request ends up into the same
> invocation, which is cpu and memory intensive.
> It might make sense to add a map in the MediaTypeHeaderProvider to store the
> result of the static valueOf method invocation.
