[resteasy] JAX-RS Client thread-safe?

Would like to inquire about the current state of thead-safety of the RESTEasy implementation of the JAX-RS javax.ws.rs.client.Client. There seems to be a discussion about how to get this into the spec, here: https://github.com/jakartaee/rest/issues/494 Apart from not yet being in the current spec, is there an "official" statement how RESTEasy handles this now? Can we already rely on the Client being thread-safe or should we keep a ThreadLocal for clients? Thanks John
