generated java source

    public ResponseEntity<List<Pet>> findPetsByStatus( @ApiParam(value = "Status values that need to be considered for filter", allowableValues = "AVAILABLE, PENDING, SOLD", defaultValue = "available") @RequestParam(value = "status", required = false, defaultValue="available") List<String> status) {

No repository file or test is named. Start by reproducing generation with the provided OpenAPI JSON and compare the generated Java source with the x-spring-paginated behavior discussed in issues 3353 and pull request 3357. Done means the extension's intended effect is reflected in the generated method or its unsupported behavior is clearly documented.
