This looks much better.
What would you think about renaming the JFR event to
"DirectBufferStatistics"? The concern I have with the proposed naming is
that it will be really awkward to extend it to support mapped buffers.
The implementation changes look okay, hopefully Erik will skim over
them. One small suggestion for for ManagementFactoryHelper is that you
can stream().collect(Collectors.toList()) to create the value for
bufferPools. You could even change it to volatile so that
getBufferMXBeans isn't a synchronized method.
