Describe the bug

Like the title says the problem is into annotation @RequestParam(required=true)

Into spring you can specify if a request param is required or not and spring ( if required is set ) and it's not passed raise a BadRequestException.

But in quarkus i've this problematic point:

Required param seems it's not supported each time I added this the app gave me this exception:

Caused by: java.lang.IllegalArgumentException: Using required @RequestMapping is not supported. Offending method is 'it.test.controller.TestController#customException'

So i need to validate each request param field manually?

Another problem is the default value, if my request param is a boolean, and i don't pass it from the caller, Quarkus set a default value. Why?

It's totally wrong..

IE:

In this example if you don't pass firstException param Quarkus set it to false.. but does not make sense because the param should be NULL so raise an exception..

Expected behavior

What I expect is that, since the RequestParam annotation is supported, its functions such as required and raising an exception if a required parameter is not passed are also supported.

Actual behavior

No response

How to Reproduce?

Download my project attached.

Run with ./mvnw quarkus:dev

Try to call the endpoint localhost:8080/test/exception without passing param firstException and can u see the default value problem

Try to add required=true into the TestController under @RequestParam annotation e you can see the error during startup
