At this point the bundle in the INSTALLED(2) state despite of previous check
for that condition and uctx is null. Also I have seen this problem when
updating the bundle with EMF using .
I think there should be a check for uctx == null.
The exception is followed by the following exception when in process of
updating bundle:
