Hi,
JMH 1.1.1 is released and available at Maven Central (thanks to Evgeny).
This is a maintenance release, nothing very important in it, no major
bugfixes, just polishing:
* https://bugs.openjdk.java.net/browse/CODETOOLS-7901042:
We now separate score and score error with \plusminus sign. This
plays well when you are copying the final lines without a header,
or paste it into a monospace-hostile destination. Example:
o.o.j.s.JMHSample_01_HW.wellHelloThere avgt 3 0.252 ± 0.023 ns/op
* https://bugs.openjdk.java.net/browse/CODETOOLS-7901043:
-prof perfasm should now be much more robust with figuring out the
Java symbol names, and be more accurate with disambiguating the
output from different compiler writer threads writing the log. If
you ever experienced trouble with noise and/or outright lies in
perfasm profiles (we did), update and try again.
* Minor touchups in Samples: fixing an odd typo reported by Ismael
Juma in JMHSample_24_Inheritance; and dodging weird performance
issue with JMHSample_03_States reported on StackOverflow.
Enjoy!
Thanks,
-Aleksey.
