Lwjgl 2.9.3 input issue.

Hi. I’m trying to do the following: I have polled the events form keyboard and I’m trying to keep track of the keys that are pressed inside my class.
Essentially my code depends on two calls: Keyboard.getEventKeyState() and char character = Keyboard.getEventCharacter().
Problem happens when a key is released - then getEventKeyState() method returns false and that’s ok, but the getEventCharacter() always returns null character. Isn’t this a bug? I’m using linux Ubuntu 15.04 and the version of LWJGL as mentioned in the topic.
