Finally found the answer to what I looking for: How to figure out what the heck Jersey was doing when matching resources. This answers it nicely:
Jersey now supports the same feature implemented in 1.1.5-ea-SNAPSHOT. Adding the following servlet/filter initialization parameter enables tracing:
<init-param> Â Â Â <param-name>com.sun.jersey.config.feature.Trace</param-name> Â Â Â <param-value>true</param-value> </init-param>
