[JENKINS-73317] JDK Parameter and Label Parameter are null from params variable

[jenkins-infra-bot]

println params

{sessionKey=8900978c-f00a-4d19-b67c-229411f75886, test=test, NODE=null, jdkVersion=null}

So text and other parameters are set.   But the Label Parameter and the JDK Parameters are not accessible.

Wanted to log this while I'm still investigating.   So fare these show up as null when tested.

  Did some experimenting adding this can basically fix it.
