Use standard decorator instead of annotation token type for highlighting Java annotation

[angelozerr]

When annotation is used in Java class,

@Deprecated
public class Foo {

}

the JDT LS semantic tokens should use decorator instead of annotation as token type, because annotation is not a standard token type, although decorator belongs to LSP specification.

I agree. The reason why annotation is used right now is that decorator was added in LSP 3.17 and so didn't exist in 3.16 when the LSP-based semantic highlighting implementation was created.

Thanks @0dinD for your answer.

I understand but now this decorator exists it would be nice to use it.

[0dinD]

Yeah, again, I agree 🙂

I was just explaining why JDT LS came to use annotation instead of decorator. Either way I'll probably send a PR to fix this at some point in the not-so-distant future if no one else does, but I can't prioritize it right now as I'm a bit busy.
