Asaf M commented on Bug JENKINS-17514

We just got this. We were using One master and two slaves (one on the master and the other on the slave). We took the slave offline, and set 0 executors on the master, and then added two new slaves, and configure them to utilize them as much as possible. The build of job on the slaves failed with this exception:

[WARNING] File encoding has not been set, using platform encoding ANSI_X3.4-1968, i.e. build is platform dependent!
