Compiled jar does not run on laptop

[Extremelyd1]

The compiled jar file does not run on the TU/e laptop, which it is supposed to run on.
This issue might be related to relative file paths to shader files in the compiled jar.

One solution could be to use buffers for the files instead of the files directly.

After further research, it had something to do with loading the shader files in the first place, but after fixing that, the error still occured, but on something different.

What's the "something different"?

The error occurs in the shader file vertex.vs and depth_vertex_cube.vs when trying to access jointIndices with an index.
