1) The new behavior breaks a previously perfectly working setup; 2) The new behavior is counter-intuitive (I wouldn't expect an SSH slave to try to set up JNLP); 3) There's no obvious option in the UI to disable this behavior. https://issues.jenkins-ci.org/browse/JENKINS-15697 On Wednesday, October 31, 2012 4:50:22 AM UTC+1, Kenny Ayers wrote: > > Hi.
