Quarkus REST: setting a LocalDate parameter to an empty value results in a 400 instead of a null parameter

[FroMage]

Given this endpoint:

@POST
public void foo(@RestForm LocalDate date){}

And this payload:

date=

I get a 400 from Quarkus REST. Probably because TemporalParamConverter doesn't handle empty strings? I think it should be set to a null value. I also assume other temporal types have the same issue.

Hi @FroMage @geoand @ia3andy
I was thinking that we can put a null check in the function convert to return null that is present inside TemporalParamConverter abstract class, does this seem like a good idea?

You can certainly give it a try
