SSHJ-SSH plugin "retry-enable" parameter causing Failed: Unknown: null

[rurobin]

After upgrading to Rundeck opensource 4.11 release, the sshj-ssh plugin errors out when having "retry-enable" parameter set to "true". For example:

project.retry-enable=true

This works fine for:

• Rundeck release 4.9 (sshj plugin version 0.1.3)
• Rundeck release 4.10.2 (sshj plugin version 0.1.4) So it only seems to be with sshj plugin 0.1.6 with Rundeck release 4.11.

Per description, the parameter should available to provide:

Enable retry on fail? Enable a connection retry when the connection fails Configure Project:project.retry-enable=false Configure Framework:framework.retry-enable=false Default value:false

the job log in debug mode:
