* array length: could we still have Nashorn APIs that return long?
Optimistic filters will deal with these appropriately, won’t they? I
guess they should since they also need to be able to handle return
values from POJO methods that return long (e.g.
System.currentTimeMillis()). Hence, you could have NativeArray.length
return “long” and let the optimistic machinery decide whether to cast
it as int or double. That would allow you to not have to box the
return value of NativeArray.length.
Yes, we could have things returning long, but it will deoptimize to
Object. OptimisticReturnFilters (which do the runtime checks) are not
used for ScriptObject properties.
Actually it would still be nice not to box, which probably means we have
to make it optimistic. Looking at this, I found that we have an
@Optimistic annotation but it looks like it isn't actually used nor
implemented.
