Hello,
I have a remote web service that I want to proxy in an OSGi framework .
For that, I use the dosgi bundle to read the ws endpoint description, and
this works fine, (see the dosgi bundle inspection at the end of the post)
Next, In an activator I track the service and when it is found , do a call
to a method of the interface/service:
________________
service.callMethod(param);
_______________________
And then this error flows:

log FrameworkEvent ERROR
________________________________________________
It seems that when the registration occurs, an exception is thrown (because
of a NPE?) and the registration stops with the service registered, see the
output of bundle dosgi inspection:
_________________________________________
endpoint.id =
http://xx.yy.zz.tt/webservice/service.php?class=hardwareMonitor
objectClass = org.xx.yy.zz.HardwareMonitor
service.id = 16
service.imported = true
service.imported.configs = org.apache.cxf.ws
________________________________________________
It seems difficult to track this bug.
