New Revision: 1723736
URL: http://svn.apache.org/viewvc?rev=1723736&view=rev
Log:
Store.load() implementations assume (in places) that getManager().getContext()
always returns a non-null and we haven't had reports of NPEs so make the
assumption consistently throughout the method.
Add a local reference to the Context's logger to shorten some of the logging
lines
