In resteasy 4 "the big resteasy-jaxrs and resteasy-client modules have been split into resteasy-core-spi, resteasy-client-api, resteasy-core and resteasy-client, with the first and second ones to be considered as public modules, for which we're expected to retain backward compatibility till next major release."
Update resteasy-jaxrs and resteasy-client to newer version (resteasy-core-spi, resteasy-client-api, resteasy-core and resteasy-client). At the moment of writing Narayana project has resteasy version 4.7.*
Update the quickstarts accordingly.
