> Since we introduced the support for Swagger (as an extension), I believe many have found it very useful.
> We are currently shipping a patched version of Swagger UI 2.0 (backed by Swagger Core 1.5), with JS support manually enabled for Matrix parameters - as such parameters are not officially supported by Swagger UI 2.0.
> Luckily, after [long discussions|https://github.com/OAI/OpenAPI-Specification/issues/69], it seems that Matrix parameters eventually found their way through the OpenAPI specification, and Swagger UI 3.0.
> In order to profit from this, we need to generate an OpenAPI 3.0- compliant descriptor, as the current /rest/swagger.json is at 2.0 but, due to the presence of matrix parameters, doesn't load with Swagger UI 3.0.
> There is an [ongoing effort in CXF|https://issues.apache.org/jira/browse/CXF-7525] to provide full support for OpenAPI 3.0, but the work has just started; moreover, this will only land in CXF 3.2 - hence our branch {{2_0_X}} will not use it anyway.
> Another approach, again provided by CXF, is the [SwaggerToOpenApiConversionFilter|https://cwiki.apache.org/confluence/display/CXF20DOC/Swagger2Feature#Swagger2Feature-ConvertingtoOpenAPIJSON], which is essentially an in-line transformer from the {{swagger.json}} we already generate, to the new {{openapi.json}} in OpenAPI 3.0 format.
