Preserving insertion order of keys on JSONObject

[mombiela]

Hello,

I know that JSON keys are unordered, but this make the transformation from JSON to XML unreliable, especially if you use xsd validation on the result. I suppose that some other formats are affected too.

I think that preserve the insertion order is a good improvement, with little impact on performance.

It should be as easy as replace java.util.HashMap with java.util.LinkedHashMap on JSONObject.

Thank you very much.

This has been tried. What happens is people make applications that depend on that ordering, which breaks interoperability.

Is the order of JSON Array [] maintained when we convert from JSON to XML?
