Greetings,

This is a preview of a large part of the source code for JEP 328 : Flight Recorder[1].

Webrev: http://cr.openjdk.java.net/~mgronlun/JEP328_FlightRecorder/Preview/webrev/index.html

It has been tested on the following platforms:

• Linux-x64

• Windows-x64

• MacOSX-x64

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.

Thank you

Markus and Erik
