Hi,
JMH 1.25 is released and available at Maven Central. This is the profiler fixes release, and it
contains these changes:
*) JFR profiler integration. Can be used with -prof jfr, pass -prof jfr:help to look for
the accepted options. It should work with every JFR-enabled JDK out there: tested with OpenJDK
8u..15u. Oracle JDK 8u would still need UnlockCommercialVMOptions. Please report problems with the
profiler, if any. Thanks to Jason Zaugg for contribution!
7902750: Add JFR profiler
*) xperfasm profiler uses xperf on Windows, and it normally requires administrator privileges. Yet,
it used to fail cryptically when privileges were not available. The UX bug was pointed by Tagir
Valeev. Should be fixed with:
7902752: xperfasm profiler should check availability properly
*) pauses profiler has the code to self-calibrate its measurement. That calibration is very slow on
Windows, and so initialization used to take minutes. Should be fixed with:
7902751: pauses profiler initializes very slowly on Windows
Enjoy!
