Inconsistent swagger generation on multiple hits

[patips34]

On error, I want to return no content from my API. I am trying to achieve like this (Picked up example from the demo), I have added 'content' to 400 as Void.class:

`@Operation(summary = "Find pet by ID", description = "Returns a single pet", security = {
@securityrequirement(name = "api_key") }, tags = { "pet" })
@ApiResponses(value = {
@ApiResponse(responseCode = "200", description = "successful operation", content = @content(schema = @Schema(implementation = Pet.class))),
@ApiResponse(responseCode = "400", description = "Invalid ID supplied", content = @content(schema = @Schema(implementation = Void.class))),

default ResponseEntity<Pet> getPetById(
		@Parameter(description = "ID of pet to return", required = true) @PathVariable("petId") Long petId) {
	return getDelegate().getPetById(petId);
}

`

In First Hit, it shows: Empty response for 400 response code.
If you hit swagger endpoint again, it will start showing up the Pet body again as response to 400.
