These changes look good to me.

I don't have any experience with JsonReadFeature class. Wondering why you only test the ALLOW_SINGLE_QUOTES constant and not the other ones?

@dougbulkley, this is really because most features aren't as relevant for filter processing. For example, JsonReadFeature.ALLOW_TRAILING_COMMA doesn't work since we explicitly don't allow that in a filter expression anyway. I suppose the numeric handling ones do fit, though it arguably doesn't add substantial coverage and could be harder to maintain if such parameters are deprecated by Jackson in the future.
