Hi,

JMH 1.11.1 patch release is available at Maven Central (props to Evgeny
Mandrikov, as usual). It includes a few minor improvements:

  * When running in IDE with standard console detached, JMH garbled the
output because of an overlook in encoding guesswork. This was discovered
and fixed by Andrei Pangin, thanks! Tracking:
    https://bugs.openjdk.java.net/browse/CODETOOLS-7901511

  * xperfasm profiler can apparently download lots .pdb files from
Internet, with no possibility to override this behavior. This was also
discovered and fixed by Andrei Pangin. Tracking:
    https://bugs.openjdk.java.net/browse/CODETOOLS-7901512

  * JMH Core Validation benchmarks now include another test,
"thread_scale", that verifies how performance of simple benchmark is
scaling with an increasing number of threads. This test is convenient to
verify the scheduling policies, power saving features, hypervisors are
not getting in the way. Tracking:
    https://bugs.openjdk.java.net/browse/CODETOOLS-7901519

  Full JAR:

http://central.maven.org/maven2/org/openjdk/jmh/jmh-core-benchmarks/1.11.1/jmh-core-benchmarks-1.11.1-full.jar

  * Also, the benchmark archetypes were not updated in archetype
catalog, which made it always use 1.10.5, even though 1.11 was available
for quite some time now.

Thanks,
