Description
I tried running the microprofile-tck/opentracing tests against a config that included the OpenAPI subsystem. It failed with an NPE:

I hit this when working on WFLY-13099. I was using a standalone.xml variant equivalent to what Galleon would generate using the cloud-server, h2-default-datasource, microprofile-fault-tolerance, microprofile-jwt and microprofile-openapi layers. It wasn't a slimmed server though.
OpenApiAnnotationScanner L934 seems to assume 'schema' will not be null. But the 'SchemaFactory.typeToSchema' method seems like it's written such that returning null is a possibility; e.g. L362 in the final 'else' block is doing a null check on the 'schema' var whose value is ultimately returned. (I don't see how else the NPE would happen other than SchemaFactory.typeToSchema returning null.)
I put Critical severity on this because I don't know anything about opentracing.war; i.e. whether it's written in a way that would be a real corner case for OpenAPI. I'm being conservative and assigning a high priority.
