NullPointerException on openJDK when loading a song

[soweliniko]

Whenever I try to load a song in beatoraja instead of loading correctly it fades to a white screen, then throws this error, after which I have to kill the process:
'''

Does it happen only on 0.4.3 and are you using only a mouse or arrow keys to select a song?

If so, please try selecting songs with the keys that you use to play songs. (For example, press 'Z' key to decide if you play with the keyboard in the default key configuration.) If it goes well, the exception is a bug that we already recognized and fixed in the master branch.

ah, that seems to fix it.
