java.lang.LinkageError: ClassCastException

Question

I do experience a really annoying problem with TestNG and RESTeasy.

I do have a class that runs several tests against an API class which uses the RESTeasy framework

Answer 1

I solved this problem by changing org.glassfish.jersey version in my pom.xml

Below is my pom.xml

 
      javax.ws.rs
      javax.ws.rs-api
      2.1.1
 
 
      org.glassfish.jersey.core
      jersey-client
      2.31
