Unfortunately, there is no workaround in GF4 (AFAIK) because in GF you cannot override classes from system-level modules with application-level classes.
As such, JAX-RS 2.0 classes are loaded from GF system modules and since Jersey 1.x does not implement all JAX-RS 2.0 APIs, you will start running into these errors. Therefore you may need to migrate your application to Jersey 2.x in order to run it in GF4.
The first thing to do is to get rid of Jersey 1.x classes in your war and change your web.xml to use Jersey 2.x ServletContainer (or switch to Servlet 3.x-based deployment-free initialization):
https://jersey.java.net/documentation/latest/deployment.html#deployment.servlet
Here are some additional hints how to migrate your application:
