Hi,
I'm testing Kojo on new Ubuntu 15.04. And it not work on java 7 and 8, while is running on 6. I tested both openjdk and oracle and they throw the same exception:
Exception: java.lang.NullPointerException thrown from the UncaughtExceptionHandler in thread "AWT-EventQueue-0"

Sombody know what is a problem?

Regards
Mikolaj

Hi Mikołaj,

Do you have a stack trace for the problem (in ~/.kojo/lite/log/kojo0.log). Where do you see the exception? Does it show up in the output window?

Does the same installation of Kojo work fine with Java 1.6?
Do you see the problem in 'English' mode also?

The log does not show a stack trace, so it's difficult for me to speculate on what might be going wrong. Do you see a stack trace anywhere when the problem occurs -- in the console (if you run Kojo from a terminal window) or in the output pane or later on in the log file?

Is there any way I can 'log in' to your system to dig into things (I don't have access to an Ubuntu 15.04 installation).

I'll be on Monday at work, and I'will check.
