Launch agents on Java 7 from Jenkins 2.60 fails without clear message

    XMLWordPrintable

Details

    Description

      Launching Jenkins 2.60 agents on Java 7 should fail with a controlled exception but it is not. The channel is just closed currently without further notice.

      This code needs fix.

      Flagged as LTS candidate as I suspect it will cause pain to users.

            Fine for Windows agents. For SSH agents we are apparently using a custom implementation which checks for Java 5!

            jglick ssh-slaves should check for Java 7, right? - as its baseline is 1.625. Or just remove the default implementation.

            For SSH Slaves, I tried, and failed, in https://github.com/jenkinsci/ssh-slaves-plugin/pull/27#issuecomment-304837590 – CC oleg_nenashev.

            No, because when it is running on 2.54+, it ought to be requiring 8. That is why it should be using the core check, and the core check should be fixed.
