      Description

      Hi Team,

      I have upgraded Jenkins to 1.6 and my slave machine went offline. Looking at logs.

      As slave.jar is meant to be launched by Jenkins typically through a remote shell like ssh/rsh. It does that step. our Linux server have dump of java not installed traditionally on the server but we use different JDK version on purpose by creating link to dump.

      On launching slave machine it tries to find the java on linux machine if not found installs automatically using script jdk.sh. The version it installs is jdk1.6 and also i do not have an option to set JDK later than 1.6 in Tools section of configuration.

      After installation i get below error not sure related to jdk or something else. I cannot install later version of JDK as it overrides everything again.

      Could you please let me know what is causing this issue??

      Is it possible that its because of this http://jenkins-ci.org/content/good-bye-java6

          Bulk issue update: The plugin connectivity is still unstable from what I see in this and other reports. Probably the recent patches in 1.24-1.25 caused some extra instability by getting rid of interlocks between agent connection and termination logic. Apparently it impacts some reconnection scenarios due to the race conditions.

          Unfortunately I do not have capacity to work on the plugin in medium-term. So for now I am unassigning issues from myself. Ivan Fernandez Calvo was very kind to take ownership of the plugin and to handle some workload in it. Probably he will have some capacity to review the backlog I was unable to triage.
