NoSuchMethodError when getting display properties using: Display.getDisplayMode().getHeight() in LWJGL

I'm trying to get the display properties for my display using: Display.getDisplayMode().getHeight(); and Display.getDisplayMode().getWidth(); but I get the following error:

What does this error mean? How can I fix it?

I've fixed the problem by replacing: 

Display.getDisplayMode().getHeight();

with:

IntBuffer w = BufferUtils.createIntBuffer(4);
IntBuffer h = BufferUtils.createIntBuffer(4);
glfwGetWindowSize(window, w, h);
height = h.get(0);

and:

Display.getDisplayMode().getWidth();

with:

IntBuffer w = BufferUtils.createIntBuffer(4);
IntBuffer h = BufferUtils.createIntBuffer(4);
glfwGetWindowSize(window, w, h);
width = w.get(0);

This fixes the problem.
