Hello Sebastian!
It’s Valerie from ZeroTurnaround. You have reported to us that there are some integration issues between JRebel and Dynamic Client from CXF 3.0.0-SNAPSHOT. To be able to deal with this situation we kindly ask you to enable trace logging and then reproduce the error again. Could you then send us your jrebel.log file? Here is a useful guide how to generate log-files [link].
We would appreciate your cooperation! Please, let us know how are you doing?
With the best regards,
Valerie
