[JENKINS-56081] Slave node environment path is duplicated

When running a slave with the path set in environment variables the (added) path is duplicated.

Steps

1. Created a slave to run on localhost by Java Web Start.


2. Add node properties environment variables, name: Path value: $Path;X;Y;Z


3. Run pipeline job that displays the path

Expected

To see the path ending with ;X;Y;Z

Actual

The path ends with :X;Y;Z;X;Y;Z

 

pipeline {

    agent {

label 'slave-1'

    }

    stages {

stage('path') {

    steps {

bat('path')

    }

} //stage

    } //stages

} //pipeline
