java.lang.NoSuchFieldError: REFLECTION

Or it could be just different versions of com.sun.xml.bind:jaxb-core and com.sun.xml.bind:jaxb-impl. Ensure they are the same across your dependency:tree.

I had -core v.2.2.11 and -impl v.2.2.6 in my project which led to the same exception. After setting both versions to 2.2.11 via dependencyManagement section everything became fine.

You have a conflict between the cxf-rt-frontend-jaxws and cxf-common-utilities libraries. Both of these provide as their dependencies com.sun.xml.bind which is the cause of your problem. So you should either exclude com.sun.xml.bind:jaxb-impl from cxf-common-utilities or remove your dependency on cxf-common-utilities.

Got the same error and found out that in my case there was a mismatch of versions of jaxb-api and jaxb-impl. The jaxb-api was included in the pom.xml with provided scope (server jboss) and the application was picking jaxb-impl from other dependency. These both were of different versions as per the stack trace.

Servlet.service() for servlet Spring MVC Servlet threw exception: java.lang.NoSuchFieldError: REFLECTION[0m    [Server:ODIN64_Server01] [31m             at com.sun.xml.bind.v2.model.impl.RuntimeModelBuilder.<init>(RuntimeModelBuilder.java:87) [**jaxb-impl-2.1.7.jar:2.1.7**][0m    .....

So adding jaxb-impl in pom and marking the scope as 'provided' made sure that both has the same version and that fixed the problem.
