> When a REST call is created from an OpenAPI spec via camel-rest-openapi, the producer sends a URL ending with an empty query part (?) even though no query parameters are set.
> *Example:*
> - API: GitHub GET /users/\{username\}/repos (with optional type query parameter)
> - Route: from("direct:listRepos").to("rest-openapi:github-api.json#listUserRepos");
> - Actual URL invoked: /users/myuser/repos?
> - Expected URL: /users/myuser/repos
> This can be a problem for services that treat /resource and /resource? differently.
> *Root cause:* {{URISupport.createURIWithQuery()}} in camel-util appends ? whenever the query string is non-null, even when it is empty. The fix is to also check {{!query.isEmpty()}} at line 446.
> *Reported against:* 4.18.2
> *Reporter:* Saravanakumar Selvaraj
