regression with /api-docs swagger in cxf jaxrs

• Fuse version: 6.2.1 R4 patch
• Fuse version : 6.2.1 R9 patch.
• Fuse 6.3

I have attached an example of CXF SwaggerFeature, which displays different swagger ui api json,

In R4:

{"apiVersion":"1.0.0","swaggerVersion":"1.2","apis":[{"path":"/HelloWolrd"}],"info":{"title":" Sample Rest Application","description":"A Sample HelloWorld Application","contact":"esb_support","license":"Apache 2.0 License","licenseUrl":"http://www.apache.org/licenses/LICENSE-2.0.html"}}[

In R9:

{"apiVersion":"1.0.0","swaggerVersion":"1.2","info":{"title":"Sample Rest Application","description":"A Sample HelloWorld Application","contact":"esb_support","license":"Apache 2.0 License","licenseUrl":"http://www.apache.org/licenses/LICENSE-2.0.html"}}

(Hit, http://localhost:10085/esm/api/v1/api-docs in the browser)

In the above notice that, '"apis":[

]' is missing to be displayed in R9 patch.

One of the ways to i see from the code is to set the SwaggerFeature#runAsFilter property to true,

<bean id="swaggerFeature" class="org.apache.cxf.jaxrs.swagger.SwaggerFeature">
<property name="runAsFilter" value="true" />

which runs the SwaggerContainerRequestFilter, populating the api-docs path.

If i do this, i can see the results as expected similar to R4.

The results are the same with Fuse 6.3 version of CXF as well inline what we see in 6.2.1 R9

I wanted to understand :

• runAsFilter existed in earlier CXF versions, however, WITHOUT explicitly defining that property, we were able to see the api-docs as i remember correctly. Why is this changed going into later CXF versions, or even in the latest CXF community codebase ?
• Do we always need to have the runAsFilter set to 'true' to display 'apis' as above ?
