You could always write custom array operations in JNI. Otherwise the answer is
no (not without a change to the JVM design, which isn't going to happen).
OTOH, it is /said/ (I find it plausible, but I can't confirm it from personal
knowledge) that the big name JVM's JITers are pretty aggressive about removing
bounds checks in the generated code, so there might not be much to gain from
special operators.
