Hi Mikael,
Are you configuring different providers on the client for every request? Or are you perhaps creating a new client for each new request?
If yes, then doing a lot of stuff to setup provider injection properly is necessary. If not, then you just found a bug, in which case I would like to ask you to file a new bug against Jersey. I have tried to pick a random E2E client test in Jersey workspace and modified it to send multiple requests (using same and different WebTarget instances) and I was not able to reproduce the behavior you are describing. In my modified test, the org.glassfish.jersey.client.ClientConfig$State.initRuntime() method gets only invoked once, with the first request.
So it seems the problem (if exists) is related to a specific use case. As such I would like to ask you to also attach a simple reproducer unit test that describes the use case and reproduces the issue.
Thank you,
Marek
