NPE on clicking Launch button in Settings Tab #1007

Open kereis opened 5 years ago

kereis commented 5 years ago

When in Settings tab, everytime you click on Launch, a NullPointerException occurs: Unhandled exception in Thread[AWT-EventQueue-0,6,main]: java.lang.NullPointerException

This happens on v1.4.17. It's unknown whether it affects older versions or not.

Reproduction steps:

  1. Open Linux/Java launcher
  2. Switch to Settings tab
  3. If you have a valid profile, click on Launch button.
  4. Check logs.

If contributions are welcome, I can take a look at that issue.

are you able to launch the game at all?

kereis commented 5 years ago

Yes you can. You just need to switch away from Settings/Options tab.
