Crash with new OpenAL sound library

Troubleshooting sound
1

I converted HelloIntersection to use OpenAL, but unfortunately it’ll crash if you fire the bullet twice. I’m experiencing an identical crash in my game also (except it crashes instantly, without even firing once).

To fix: the setPosition method in Sample3D in the OpenAL package needs to be set to this:

public void setPosition(float x, float y, float z){
       position.clear();
        position.put(x);
        position.put(y);
        position.put(z);
        positionChanged=true;
       
    }
