NPE on running some slaves of a matrix build - failure with no explanation
My guess would be that despite isUnix being set in a synchronized{} block, when isUnix() is not synchronised, so a second thread getting the value might be getting an out of date value.

Oleg Nenashev commented on JENKINS-23305 NPE on running some slaves of a matrix build - failure with no explanation Sorry, I've missed the previous message... trejkaz is right.

trejkaz commented on JENKINS-23305 NPE on running some slaves of a matrix build - failure with no explanation Definitely using 1.566, but I agree, if that's the code running in 1.566, I don't see where there can be an NPE, unless there is some unboxing going on which is not evident by seeing just that fragment.

Are you sure that you use 1.566?
I don't see any NPE chance in https://github.com/jenkinsci/jenkins/blob/jenkins-1.566/core/src/main/java/hudson/model/Slave.java
