Description

We have a problem with this build
https://builds.apache.org/job/maven-box/job/maven-surefire/job/master/6
There are two Build Failures:

1. testForkModeOncePerThreadTwoThreads(org.apache.maven.surefire.its.ForkModeIT): number of different pids is not as expected expected:<2> but was:<1>
2. test[junit4-twoForks-ff1](org.apache.maven.surefire.its.FailFastJUnitIT): wrong number of errors expected:<2> but was:<1>

The ForkModeIT missed delays in JUnit test methods, but the FailFastJUnitIT code is ok and the only problem is virtual CPU scheduler. We expect that two JVMs start up within 1.5 second and most probably this did not happen.
