    Description

      Jenkins failed some test on 2 configurations out of a 5-configuration matrix build, with the other 3 builds completing normally. Both failed slaves leave no additional information for diagnosing the root cause:

      13:49:24 Started by upstream project "fast-tests" build number 920
13:49:24 originally caused by:

      JENKINS-21999 seemed to be a similar issue but the line numbers have changed and that issue was fixed, whereas this issue still occurs.

            It's weird how a job can be scheduled for a node before it could be determined whether it's Unix.

            My guess would be that despite isUnix being set in a synchronized{} block, isUnix() is not synchronised, so a second thread getting the value might be getting an out of date value.
