Hi Markus,
I'm trying to compile the patch but get following errors:
Compiling 1616 files for jdk.localedata
.../hs/src/jdk.jfr/share/classes/jdk/jfr/internal/SecuritySupport.java:60: error: package jdk.internal.misc is not visible import jdk.internal.misc.Unsafe; ^ (package jdk.internal.misc is declared in module java.base, which does not export it to module jdk.jfr)
.../hs/src/jdk.jfr/share/classes/jdk/jfr/internal/SecuritySupport.java:61: error: package jdk.internal.module does not exist import jdk.internal.module.Modules; ^ .../hs/src/jdk.jfr/share/classes/jdk/jfr/internal/JVM.java:31: error: package jdk.internal is not visible import jdk.internal.HotSpotIntrinsicCandidate;
etc.
Any ideas of what could be wrong?

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/JEP328FlightRecorder/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 INCLUDETRACE to INCLUDEJFR. 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 [1] http://openjdk.java.net/jeps/328 PS the patch was generated from the hs repository [2] using change [3] as parent.
