Specify case sensitivity of enum values

[sfackler]

conjure-java currently normalizes enum values to uppercase when deserializing, so the JSON value "one", "One", "ONE", etc will all successfully deserialize to an EnumExample.ONE (and unknown variants will be upper-cased).

This behavior isn't actually specified, however.

The wire spec states that string comparison should be used when comparing enums and the language spec state that all enum values must be UPPERCASE. It follows that "ONE" is valid but "One", "one" are invalid. The documentation could probably be a little more explicit about the handling of such cases.

It does seem like you've found conjure-java being overly permissive. We should follow up with test cases in conjure-validation and then fix things up in conjure-java

Cool - should we close this and open issues on conjure-java/conjure-validation?

ya if you could that would be great!
