In 'Prepare an environment for the job', if 'Properties Content' is set to the following:

TOOLS=C:\MyDir
JAVA_HOME=${TOOLS}/JDK/jdk
Path=${JAVA_HOME}/bin;${Path}

Path will not be changed but TOOLS and JAVA_HOME will; however if 'Properties Content' is set to the following:

TOOLS=C:\MyDir
JAVA_HOME=C:\MyDir/JDK/jdk
Path=${JAVA_HOME}/bin;${Path}

all three variables will be set.

This behavior showed up when I upgraded from 0.15 to 0.18. Attached is a job config.xml that exhibits this problem
