During our upgrading to the latest karaf 4.4.1 I found a problem with CXF
3.5.3 and Swagger UI (3.52.5). We dynamically export openapi descriptions
so when developers
display a webpage localhost:8181/cxf they are able to display Swagger UI
for a specific endpoint.
Everything worked fine with Karaf 4.3.6 but now I can see this exception:

I also checked Swagger UI bundle and I could see that a file
META-INF/resources/webjars/swagger-ui/3.52.5/index.html existed.
Within our feature we install these dependencies:
<bundle>mvn:org.webjars/swagger-ui/3.52.5</bundle>
<feature>cxf-rs-description-openapi-v3</feature>
Could it be a bug?
