Shaders are done on the GPU rather the CPU which makes it a whole lot faster and less CPU intensive like which you are seeing.
Under research, I found that the default Java 2D library uses hardware accelerations based on what is supported. The code probably makes it so that it chooses whichever highest OpenGL version you support and uses it. Your implementation probably only uses a single version.
I'm not talking about my implementation, because I dont have one.
I was just asking because I've seen many java engines that use more CPU when using opengl compared with software rendering. One example is the well known mmorpg Runescape. And what I was going to say after his answer, was that since 2d pokemon games don't require an high fps value, he can put a cap on the fps and stay with java2d as it will use less CPU than the opengl implementation while having the same drawing performance.
