Describe the bug

Locale with BCP 47 extensions are not serialized / de-serialized as expected using ObjectMapper.

Version information

Which Jackson version(s) was this for?
All Jackson versions.

To Reproduce

If you have a way to reproduce this with:

Brief code sample/snippet: include here in pre-formatted/code section

Locale locale = Locale.forLanguageTag("en-US-x-de

I have a TypeIdResolver implementation which works around generic type erasure to allow marshaling/unmarshaling of a parameterized type. This works fine when the underlying parameterized type maps directly onto a JSON type e.g. java.lang.Double but when it's a type that needs to be converted to a JSON string e.g. java.time.LocalDate then my TypeIdResolver is asked for a type and I can eit

I do most of my development against 2.12 because of sbt, but during CI we still build against 2.13 to test both the generator as well as the generated code against 2.13.

As a result, a lot of warnings have appeared around deprecated syntax and deprecated stdlib imports, these should be resolved.

This is a fairly straightforward change, you can see some of the warnings by doing

Tools like jq are focused predominantly on their use on the command line, but have a lot of limitations (and bugs!) that jslt doesn't. This is a compliment to jslt btw. :)

To properly replace the usage of jq with jslt, we would like to be able to have some more flexibility with the ways of specifying the input parameters as well as the output.

• Specifying JSON input or JSLT transform input

InstantSerializer doesn't respect any of the following standard Jackson configuration settings:

ObjectMapper#setDateFormat
@JsonFormat(pattern) on an Instant
others?

Instead, I have to create and manually override the default InstantSerializer registered by the module.

This isn't well documented and is definitely confusing when using the library.
Can we make InstantSerializer

It would be nice to have a CSV feature similar to JSON feature JsonGenerator.Feature.WRITE_NUMBERS_AS_STRINGS. Enabling of the feature by mapper.enable(JsonGenerator.Feature.WRITE_NUMBERS_AS_STRINGS) doesn't work for CSV.

I want to write an object of this class:

data class TestData(
        val integer: Int,
        val float: Float
}

as
"1","1.234"
not as
1,1.234
