Yes, Java (the X11 Java2D pipeline to be precise) relies a lot on shm-pixmaps to do rendering with the CPU, however now with EXA and the new NVidia drivers ShmPixmaps are basically gone. You can try to use the following command line: -Dsun.java2d.pmoffscreen=false
This way it switches to pure software-rendering which is definitily better than half-accalerated.
I am working on a project which creates an XRender based Java2D backend. It tries to accalerate as much as possible, and therefor fast CPU access isn't needed anymore.
With the new 180.80 drivers it works really well, thanks a lot to the Nvidia developers

I'll soon distriobute pre-build packages for testing purposes, I would be happy if there would be some interest in testing these builds.
Thanks, Clemens
