This is a preview of a large part of the source code for JEP 328 : Flight Recorder.
It has been tested on the following platforms:
We are planning to send out the code for full review in a couple of weeks.
At this point, we are preparing changes to move to a single backend, as suggested in the JEP.
These will encompass the following:
1. Rename macro INCLUDE_TRACE to INCLUDE_JFR.
2. Remove flag -XX:[+|-]EnableTracing.
3. Cleanup unused elements and attributes by restructuring the trace xml files.
4. Move code under hotspot/share/trace to hotspot/share/jfr/metadata.
