the window or has pressed the ESCAPE key. Run the rendering loop until the user has attempted to close creates the GLCapabilities instance and makes the OpenGL LWJGL detects the context that is current in the current thread, OpenGL context, or any context that is managed externally. This line is critical for LWJGL's interoperation with GLFW's GlfwSetKe圜allback(window, (window, key, scancode, action, mods) -> // the stack frame is popped automatically It will be called every time a key is pressed, repeated or released.

Throw new RuntimeException('Failed to create the GLFW window') Window = glfwCreateWindow(300, 300, 'Hello World!', NULL, NULL) Create the window - This is where the problem is GlfwWindowHint(GLFW_RESIZABLE, GLFW_TRUE) // the window will be resizable GlfwWindowHint(GLFW_VISIBLE, GLFW_FALSE) // the window will stay hidden after creation GlfwDefaultWindowHints() // optional, the current window hints are already the default Throw new IllegalStateException('Unable to initialize GLFW') Most GLFW functions will not work before doing this. GLFWErrorCallback.createPrint(System.err).set() will print the error message in System.err. Terminate GLFW and free the error callback So I got my basic OpenGL Java demo code working again now with LWJGL 3 and SDK 0.7.0.0 :) I will try and spend some time on some more modern OpenGL approach soon. Free the window callbacks and destroy the window ('Hello LWJGL ' + Version.getVersion() + '!') What is going on here, and how can I fix it? I was confused as to what this meant because I didn't think the init() method was running in any thread other than main, and so I added a line to print which thread it was running in, and sure enough, it printed Thread. 10:20:02.145 java *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '+ is only safe to invoke on the main thread.

I tried to run it myself and found that it errored with the following: I am new to using LWJGL (and relatively so to Java in general) and as such, I was reading their page on getting started where they supplied an example Hello World program.
