Freeman Fang commented on SMX4-253:
-----------------------------------
this issue actually is caused by the the upgrade of pax.web.extender from 0.3.0
to 0.5.0
in the currently used 0.5.0, it need a service property "servlet-name" for all
osgi services which implement javax.servlet.Servlet interface
if no servlet-name, then get exception like
java.lang.NullPointerException

at org.apache.felix.framework.Felix$1.serviceChanged(Felix.java:622)
and in the org.ops4j.pax.web.extender.whiteboard.internal.tracker.ServletTracker
mapping.setServletName(servletName.toString().trim());// this line cause the
NPE.
In the lastest pax.web.extender snapshot, it add the NULL checker to avoid it.
We can add the "servlet-name" for cxf-transport-osgi servlet osgi service to
avoid the NPE also.
