I have a very simple BPM workflow having inline javascript for Execution Listener. Although while starting a process it shows error The process could not be started.: Cannot instantiate process definition multiInstanceDemo:1:a27d4788-e7dd-11eb-b4b6-00090ffe0001: Can’t find scripting engine for ‘javascript’: scriptEngine is null
I’m attaching BPMN diagram and log. Request some heads up on this matter.
as Nashorn was deprecated and removed in JDK15 as @aravindhrs mentioned, we have introduced GraalVM JS in our distro in 7.16.0-alpha3 to line up with JDK15.
So, if you can wait until 7.16.0 Release to upgrade to JDK15, this could be your way of developing the platform.
