Caused by: java.lang.IllegalStateException: GLFW windows may only be created on the main thread and that thread must be the first thread in the process. Please run the JVM with -XstartOnFirstThread. For offscreen rendering, make sure another window toolkit (e.g. AWT or JavaFX) is initialized before GLFW.

Multithreading Note:

(A) window/context creation (B) running the event loop that dispatches events for the window (C) making the context current in a thread.
