Hello people.

I am attempting to implement OpenGL based on some reference material. After adding all the necessary code,
I attempted to a run an unit test (the code of this can be found here: https://pastebin.com/B5sKmU20.)
However, I get an error at line 81 " int res = glContext.makeCurrent();", the full error is disclosed below.
Can someone help me resolve this, I couldn't find any other threads of people experiencing similar issues.

Thanks in advance :)

Java version:
1.8.0_131 (1.8.0 update 131)
