Hi,

jcstress 0.4 is released and available on Maven Central. It includes the following fixes:

 *) Forked VMs now have the heap size set via MaxHeapFraction. This helps to run on massively
multicore machines faster without depleting the physical memory:
  https://bugs.openjdk.java.net/browse/CODETOOLS-7902026

 *) "sanity" mode now forks, which allows setting aggressive JVM options for the tests, without
compromising the host JVM
  https://bugs.openjdk.java.net/browse/CODETOOLS-7902025

 *) Timeout handling is more relaxed, allowing "interrupt" tests to have less false negatives:
  https://bugs.openjdk.java.net/browse/CODETOOLS-7902024

 *) Tasks are now shuffled between executor threads to better randomize the tests
  https://bugs.openjdk.java.net/browse/CODETOOLS-7902023

 *) jcstress used to omit samples gathered during sanity tests, and sometimes interesting things
happened there:
  https://bugs.openjdk.java.net/browse/CODETOOLS-7901970

Enjoy!

Thanks,
-Aleksey
