Sergey Beryozkin commented on CXF-7142:
---------------------------------------
I've added NoClassDefError catch blocks - note CXF Core will do the right log
messages if Aries is missing or was not initialized properly so I did not add
all the same logging messages to other 10 or so Activators to minimize the
noise
> Blueprint mandatory in OSGi
