Failing to run in browser - undefined (reading 'charCodeAt')

[ApKatos]

I am working on a Vue3 application bundled with Rollup Vite. I have a working module which runs correctly using ts-node, however, when I try to run it in the browser it fails. I tried to debug it, but even this minimal example resolves in:

TypeError: Cannot read properties of undefined (reading 'charCodeAt')

import { java } from "jree";

export function testBrowserString() {
  let str = new java.lang.String("TEST_STRING");
}

I am importing this code example in my Vue component and trying to call this testBrowserString on mounted. I tried to call other methods eg. java.lang.Integer and java.lang.StringBuilder, etc. and it also fails. Is this a jree issue or is it a problem on my side? The documentation claims it should be compatible with browsers (except stated file modules, which I am not planning to use anyway).

I have not really worked out all details for running in a browser. In this case the code uses the path node module, which is obviously not available there.
