Micronaut 4 throws 404 error for an endpoint having special characters in path parameter

[AshPrajapati]

Expected Behavior

When we hit the API with special characters i.e. http://localhost:8080/search - (Js - on). Micronaut 3 responds with success(200). We should expect success from Micronaut 4 for the example API call.

Actual Behaviour

But we are getting 404 on calling http://localhost:8080/search - (Js - on).

Steps To Reproduce

1. Create a controller with the Path parameter
2. In the path parameter, we should pass special characters when we call the API

Environment Information

• Operating System: Windows 10
• JDK: corretto-17

Example Application

https://github.com/AshPrajapati/Micronaut-Special-Character-URL-Issue/tree/micronaut-4

Version

Version: 4.4.0

Note: We have created a GitHub repository that contains two branches(i.e. one for Micronaut 3.0 and another for Micronaut 4.0). We can use the gradle run command to run the application.

Change @Get("/{message}") to @Get("/{+message}") in your EchoController and it will work again.
