BBB GPIO access with java


Did someone know a good free LIB for accessing the GPIO from the Beaglebone Black?
I know:

But not sure if I make mistakes … very often I cannot inititalize:
private final Board board = Platform.createBoard();

This happens, when I destroy my class. I do before this:

And add a new instance of my class.
Then it often happen that the command give an error.

So is there another lib for control GPIO in Java?

Thank you!

Any file system linrary would work, with the knowledge of how sysfs works.

Any file system LIBRARY . . . . typo.
