Java records cannot be used for request beans with @PathVariable

[lbkulinski]

Expected Behavior

I expect to be able to use Java records with @RequestBean and @PathVariable for API endpoints in the same way that I can declare a POJO.

Actual Behaviour

Instead, I get the following compilation error:

java: The route declares a uri variable named [id], but no corresponding method argument is present

Steps To Reproduce

1. Clone the provided repository
2. Run the Micronaut application
3. See the following compilation error: java: The route declares a uri variable named [id], but no corresponding method argument is present

Environment Information

• Operating System: macOS Ventura 13.0
• JDK (I presume this would still occur on non-ea builds): openjdk 20-ea 2023-03-21
  OpenJDK Runtime Environment (build 20-ea+21-1545)
  OpenJDK 64-Bit Server VM (build 20-ea+21-1545, mixed mode, sharing)

@yawkat Is this fix available in 3.8.0-SNAPSHOT? I recently picked a project back up that was trying to use it, and appear to be having issues with using @PathVariable and records still. The original example now compiles, but I am now getting the following when making a request:

{
    "message": "Bad Request",
    "_links": {
        "self": {
            "href": "/api/example/1",
            "templated": false
        }
    },
    "_embedded": {
        "errors": [
            {
                "message": "Required argument [Integer id] not specified",
                "path": "/id"
            }
        ]
    }
}

This occurs when I POST to /api/example/1, where 1 would be the value for the required id path variable. I have update the following repository, where you should be able to see the issue: https://github.com/lbkulinski/record_bug_example

Thanks!
