Activiti error:using JavaScript in .bpmn20.xml

Question

I tried to use JS like that in Activiti process:

<process id="test_model" isExecutable="true">
        <startEvent id="414-013"></startEvent>
        <scriptTask id="javascriptScript" name="jsTask" scriptFormat="JavaScript" activiti:autoStoreVariables="false">
            <script><![CDATA[
                var my = "Bla bla bla";
                console.log(my);
            ]]></script>
        </scriptTask>
        <endEvent id="0DC2EF"></endEvent>
    </process>

This xml uploaded perfect, but when I try Start Process, I have error:

Reference Error:"console" is not defined at line 3

Also I tried create new Form in js:

var form = new FormData();

And again I have the same error.

What I`m doing wrong? In what this error?

Thank you for help

By default JavaScript is included in every JDK and as such doesn’t need any additional jars.

Default JavaScript engine is Rhino (JDK6, JDK7) or Nashorn (JDK8+) depending on JDK version. These engines do not support browser APIs and therefore don't provide browser specific objects like console. The main purposue of the bundled engines is scripting java, see Java Scripting Programmer's Guide

For output use print function

 var my = "Bla bla bla";
 print(my);
