We can get rid of MessagePropertySettingInterceptor, which is not actually required anymore (also considering JBWS-3920 changes) because it's more efficient to set the "org.apache.cxf.ws.addressing.decoupled_fault_support" property in the Bus instead of in every exchanged message. The MAPCodec does MessageUtils.getContextualProperties to read the property, so the prop set in the Bus is read and can be overridden by manually setting a different value in the messages.
