Microprofile REST Client examples do not deploy on 5.192

[edthorne]

After removing the POM's erroneous reference to ${payara.miro.maven.version} and executing the example using the instructions, the following error and stack trace is observed:

I tried every version from 5.182 through 5.192 and all of them work except 5.192. I haven't been able to pinpoint the cause but I question if the MP REST Client interfaces should be discovered and validated by Jersey during application deployment. It's my belief that the JAX-RS annotated interfaces are being discovered and validated and made part of the application.

This is also demonstrated in the inclusion of configured client paths in the application WADL and output Payara Micro URLs on server start up. While this can't be seen in the examples when they work, they are easily visible in an application that accesses another application's resources remotely. The remote URLs are included in the local application's WADL. I did not see this behavior on 5.191 but do see this behavior on 5.192. I'm going to work on a reproduction case independent of this report on the existing example.
