> I have a layout which iterates through message parameters, however Message.getParameters causes allocation on many implementations.
> It appears that ReusableMessage.swapParameters is supposed to fill this gap, however some messages types do allocation when this is invoked (see ReusableParameterizedMessage) which isn't helpful for access on a single thread where we don't want to take ownership of values.
> I've put together a proposal for an accessor similar to MapMessage:
