1624693 - Angular (TypeScript) application from JHipster 6.8.0 do not work in Firefox Developer Edition

Status: RESOLVED DUPLICATE of bug 1628719

(Core :: JavaScript Engine: JIT, defect)

Description

[prorokxp]

Attachment: jhipster-angular-bug.png

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:75.0) Gecko/20100101 Firefox/75.0

Steps to reproduce:

1. generate jhipster application with Angular frontend (React frontend works well by the way) with "jhipster.cmd" command
2. npm start
   to run angular application

Firefox Developer Edition 75.0b7 (64-bit) on Windows 10

Actual results:

Browser gives me an error:
TypeError: clazz.decorators is undefined

Expected results:

Its hard to say where is the error. Because you know, its an angular application with typescript, webpack and ES processors.
But there is one fact - it actually works in all browsers except. Firefox Developers Edition 75.0b7 (64-bit). And it works well in Firefox 74.0 (64-bit)

So I think the problem is about compatibility with beta version of Firefox. I hope it can be fixed.
I'm glad to provide additional information, if you need it

Is it possible to provide a test page so we could investigate this problem?

Comment 2

[Simon Leiß]

This error now also occurs on Firefox 75.0.

I set up an test site so you can investigate: https://bugzilla-report.simon-leiss.de/

Please not that the websites functionality (like login) is not working, but that's intended as thats only a demo site.

Just to add some more information to what Simon mentioned, this appears only on Firefox when used in conjunction with Angular 9 and Webpack bundling with es2015; more information and exact code to replace it could be found at https://github.com/jhipster/generator-jhipster/issues/11566. If you guys need any further help in reproducing it let us know. :smile:

Setting javascript.options.blinterp=false fixes the issue.

Probably a dupe of bug 1628719.
