The bottleneck seems to be the context creation which is not something specific to JOGL. Therefore, if you created OpenGL windows directly in C with a single context per window, you would hit the same limit maybe a very little bit later because Java2D may create an OpenGL context. The maximum total number of contexts is hardware-dependent both in OpenGL and Direct3D.
