A DESCRIPTION OF THE PROBLEM :
This is an upstream bug report for https://josm.openstreetmap.de/ticket/14905

As per Quality Outreach please add label "josm-found" to this report.

One of our users face the following error when initializing Nashorn:

The Javascript code given to Nashorn can be found here:
https://josm.openstreetmap.de/export/11595/josm/trunk/data/validator/opening_hours.js

The code loading this script with Nashorn is as follows:

ScriptEngine ENGINE = new ScriptEngineManager().getEngineByName("JavaScript");

            try (CachedFile cf = new CachedFile("resource://data/validator/opening_hours.js");
                 Reader reader = cf.getContentReader()) {
                ENGINE.eval(reader);
                ENGINE.eval("var opening_hours = require('opening_hours');");
                // fake country/state to not get errors on holidays
                ENGINE.eval("var nominatimJSON = {address: {state: 'Bayern', country_code: 'de'}};");
                ENGINE.eval(
                        "var oh = function (value, mode, locale) {" +
                        " try {" +
                        " var r = new opening_hours(value, nominatimJSON, {mode: mode, locale: locale});" +
                        " r.getErrors = function() {return [];};" +
                        " return r;" +
                        " } catch (err) {" +
                        " return {" +
                        " prettifyValue: function() {return null;}," +
                        " getWarnings: function() {return [];}," +
                        " getErrors: function() {return [err.toString()]}" +
                        " };" +
                        " }" +
                        "};");
            }

This code has not changed in the past 3 months and we have thousands of users who didn't face this error before, so we assume it's a recent regression (8u131 maybe?) that involves non-deterministic behaviour.
