Resource method String param annotated with @RestForm not decoded automatically

[mkouba]

Describe the bug

It seems that a String resource method param annotated with @RestForm is not decoded automatically. AFAIK the spec version of this annotation, i.e. @FormParam is decoded unless used together with @Encoded.

I am surprised we don't have any TCK issues with this...

@FroMage any idea?

[FroMage]

Also surprised. I honestly don't remember how we implemented this.

[FroMage]

Well, I don't remember because I didn't write this part, check out FormEncodedDataDefinition and/or ask @stuartwdouglas ;)

Do you have a reproducer? The spec and RestForm code should be exactly the same, and the TCK does test this.

I'll try to prepare a reproducer today.

@stuartwdouglas Here it is: https://github.com/mkouba/issue-23055

There is a simple form in the index.hml -> enter a space-separated value in the input field and submit the form.
