Parameter substitution has error if a parameter value contains an unquoted dollar ($)

Current Situation

Parameters of JITL jobs can be substituted by the values of other parameters.

<param name="foo" value="world"/>
<param name="bar" value="hello \${foo}"/>

If the value of foo in the above example has a $ inside then the following error raises:

JSJ_F_0060: error occurred reading Parameter from Variable_set : Illegal group reference

Desired Behavior

Substitution should work without above error

Typical Use Case

If you have for example the YADE job in a job chain with a file_order_source to transfer the file then you have to set the YADE parameter file_path with the value of the file_order_source parameter scheduler_file_path

<param name="file_path" value="\${scheduler_file_path}"/>

Unfortunally, a file order source can have a $ in its parameter scheduler_file_path, e.g. \\otherServer\c$\temp\test.txt so that above error is raised.

Workaround

Use a pre-processing to set the YADE parameter file_path

    <monitor  name="set_file_path_with_file_order_source" ordering="0">
        <script  language="javax.script:ecmascript">
            <![CDATA[
function spooler_process_before(){
    var orderParams = spooler_task.order().params();
    orderParams.set_value( "file_path", orderParams.value("scheduler_file_path") );
    return true;
}
            ]]>
        </script>
    </monitor>
