SSL SunCertPathBuilderException

[MaSven]

I also opened this issue here 7948.
It seems like this is build with openjdk10 and arduinoIDE is not supporting java9+. Dont know if this is the problem or its just the jre used by this flatpak.

Thanks for opening upstream, yeah. Looks like this needs openjdk-8. There isn't an easy flatpak SDK extension for that at the moment but obviously it'll have to be done by someone.

I tried to bunlde openjdk8 with the arduino ide. But i dont know how to bundle the gtk2 lib with it since java8 depends on it. Also the ArduinoIDE needs this because it is setting the swing.defaultlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel. You can have a look here for it fork.

Hi, would it be possible to try building with the latest openjdk11 extension?

I have fixed some SSL problems recently, and would love if this started working :-)

This is being build with openjddk11 since #10
