--------------------------------------------------------------
Hey [~mattyb149] - thanks for looking at this (and BTW all your many posts &
blogs I've learned so much from!!)
Unfortunately this is _not_ a dupe of the copy/paste issue. The failure I get
is evident after following the workaround noted in that issue.
Also, affects the script when it is a script file.
The issue here is that I cannot access the classes of the included module (if I
remove the attempt to access StringEscapeUtils but leaving the module reference
in place then the script runs fine).

> Reporter: Armin Aschoff
> Priority: Critical
> Fix For: 1.17.0, 1.16.1

>
> Create a new InvokeScriptedProcessor.
> Set Module Directory: ./scripts/jars/commons-text-1.6/
> - have tried setting absolute & relative paths, paths to directories, paths
> to jar files, different versions of commons-text, trailing slash/no trailing
> slash, etc. No differences
> Set script engine ECMAScript
> Write js script that tries to call a static method in commons-text. Script
> can be either script file or script body, no difference
> Always get ClassNotFoundException error:
> {noformat}
> Component is invalid: 'ScriptValidation' validated against
> './scripts/testCsv.js' is invalid because Unable to load script due to
> java.lang.ClassNotFoundException:
> org.apache.commons.text.StringEscapeUtils{noformat}
>
> Have tried Java.type and Packages. to try to access the class.
> Any/all help much appreciated as rapidly losing remaining hair!
