While JME specifically reserves the value -1 for invalid IDs:
I believe negative IDs in general don't justify throwing an exception.
The OpenGL documentation doesn't specify range of values for a texture name, only that they are GLuint:
- https://registry.khronos.org/OpenGL-Refpages/gl4/html/glGenBuffers.xhtml
- https://registry.khronos.org/OpenGL-Refpages/gl4/html/glGenTextures.xhtml
According to the OpenGL spec, GLuint is at least 32 bits, so values > 0x7fffffff will produce negative values in a Java int.
I think the tests in lines 105 and 132 should be specifically for == INVALID_ID instead of <= 0.
