      Description

      Hi,

      I'm unable to start/connect slave machine, using JNLP, after installing version 2.27 on master + new 3.0 slave.jar on slave computer. Installed Java 1.8.111.

      I've enabled Java Web Start agent 3 and 4 in Configure Global Security, but to no avail. All I'm getting is an error "Local headers refused by remote: CPRAN03 is not a JNLP agent" followed by number of exceptions and even version 3 and 2 of JNLP agent fails to start. Is there something else I need to configure in latest Jenkins 2.27?

      C:\Jenkins>call "C:\Program Files (x86)\Java\jre1.8.0_111\bin\java.exe" -Xrs -ja
      r "slave.jar" -jnlpUrl http://cpjen01:8090/computer/CPRAN03/slave-agent.jnlp -se

            I have my own class that i extend for SSH and JNLP launcher implementation. Core isn't backward compatible in terms of 2.X version. If you want to do something breakable please schedule it for 3.0 jenkins.

            jenkins.slaves.DefaultJnlpSlaveReceiver.disableStrictVerification=true
            Exectuing this in groovy as a workaround helped me. Thanks Ryan Thornton.
