I suspect dropping `static final` from these `VarHandle`-s would degrade performance, as some internal checks in `VHs` would not constant-fold. Do you need these in isolation, or can you lazily-initialize them all at once? You can use "holder class" pattern like: static class VHHolder { static final VarHandle xAdvanceHandle = ... } ------------- Changes requested by shade (Reviewer).
