Issue: micronaut-projects/micronaut-core#1812

Task List

• Steps to reproduce provided
• Stacktrace (if present) provided
• Example that reproduces the problem uploaded to Github
• Full description of the issue provided (see below)

Steps to Reproduce

1. Create a declarative client in kotlin like the following:

interface ExampleOperations {
    @Get("{?test}")
    fun get(@QueryValue test: Boolean): Boolean
}

2. Attempt to build the project

Expected Behaviour

The project should be able to compile and allow a non nullable Boolean @QueryValue.

Actual Behaviour

We get the following compilation error expecting the Boolean property to be Optional

error: The uri variable [test] is optional, but the corresponding method argument [boolean test] is not defined as an Optional or annotated with the javax.annotation.Nullable annotation.
    public boolean get(boolean test) {
