[BUG] JAVA OpenApi generator - multiple content types with different MIME types

Hello everyone,
are multiple content types with different MIME types supported by JAVA OpenApi generator, as in the example below?
We are using version 6.0.1 of the generator.
Generating gives the warning:

[WARNING] Multiple schemas found in the OAS 'content' section, returning only the first one (application/text)

API generated for this:

@RequestMapping(
        method = RequestMethod.GET,
        value = "/response/{p1}",
        produces = "application/json"
    )
    ResponseEntity<String> getResponse(
         @PathVariable("p1") String p1
    );  

If multiple content types with different MIME types are supported, can you please provide a working example.

Start by running the Java OpenAPI generator at version 6.0.1 with the OpenAPI document and response definition shown in the issue, then inspect the generated getResponse method and the warning about multiple schemas. Compare the generated produces value with both declared MIME types; done means the supported behavior is established and covered by a reproducible example or regression test.
