[ldclakmal]

Description:
HTTP resource auth annotations do not get applied for paths with dot (.) and special chars (ex: $, @).

Steps to reproduce:
The HTTP resources defined in the following example is not secured even-though it is annotated with auth configurations.

import ballerina/http;

http:JwtValidatorConfig config = {
    issuer: "wso2",
    audience: "ballerina",
    signatureConfig: {
        jwksConfig: {
            url: "https://localhost:9445/oauth2/jwks",
            clientConfig: {
                secureSocket: {
                    cert: "./resources/public.crt"
                }
            }
        }
    }
};

service /foo on new http:Listener(9090) {

    @http:ResourceConfig {
        auth: [
            {
                jwtValidatorConfig: config
            }
        ]
    }
    resource function get .() returns string {
        return "Hello, World!";
    }
    
    @http:ResourceConfig {
        auth: [
            {
                jwtValidatorConfig: config
            }
        ]
    }
    resource function get foo\$bar\@() returns string {
        return "Hello, World!";
    }
}

$ curl http://localhost:9090/foo
Hello, World!

$ curl http://localhost:9090/foo/foo%24bar%40
Hello, World!
