The host-side application could already be written using Java, atleast for OpenCL applications[1] (The kernel--that is, the GPU code--was still written in OpenCL). My only concern is that Java will make it more difficult to find out exactly what's going on in the kernel code, and hence more difficult to optimise.
Now, this also doesn't solve the issue of needing to consider the parallel architecture when coding the kernel to actually make use of the hardware. Nevertheless, kudos to the guys behind this.
