JCStress 0.13

[Aleksey Shipilev]

Hi,

JCStress 0.13 is released and available on Maven Central. This is useful for those who use JCStress 
as Maven dependency. This release further improves harness reliability and testing performance.

It comes with the following improvements and bugfixes:

  *) Fidelity: The infrastructure now does smaller strides, greatly increasing collision chances for 
many tests, without sacrificing much of the testing performance
   7902964: jcstress: Introduce short-stride checkpointing for more frequent collisions
   7902974: jcstress: Footprint estimator should balance both stride count and stride size

  *) Reliability: Many fixes for split compilation that keep actor methods from compilation on 
unintended levels; if you ever seen outcomes on pure Interpreter that make little sense, these 
should fix the oddities
   7902971: jcstress: Interpreted mode match is incorrect
   7902972: jcstress: Worker thread methods should not inline further calls
   7902973: jcstress: Compiler directives should include binary, not qualified class names
   7902976: jcstress: Force actor methods compilation mode to prevent escapes

  *) UX: Improved console logging
   7902965: jcstress: Enhance FREQ precision to 0.01%
   7902962: jcstress: Print merged results at the end of the run

  *) Compatibility: JDK 17 deprecated SecurityManager, better Unsafe compatibility
   7902975: jcstress: JDK 17 cannot cleanly compile due to SecurityManager deprecation
   7902967: jcstress: Rehash Unsafe usages in infrastructure and tests

Enjoy!
