So i am experiencing a weird problem currently. I want to use WorldWind in my Java application but when i want to create a WorldWindowGLCanvas the thread with which i want to create it just "freezes" and does nothing. It throws no error message or anything that could give a clue to what the problem is. There is just no window opening. I also tried one of my older OpenGL Projects that use a GLCanvas and the same problem happens there. No window opens up but it worked before.
If i comment the creation of the GLCanvas or WorldWindowGLCanvas out and just start the JFrame i see the JFrame. So i guess it must have something to do with OpenGL.
Some Info
My IDE is: IntelliJ Ultimate
Graphics Card is: Intel HD graphics 520(newest driver installed)
Jogl version is: 2.3.2

Maybe someone experienced something simillar and can help me ^^? If i missed some info that you may need feel free to ask for it.
