Simon Nash resolved TUSCANY-3588.
---------------------------------
Resolution: Fixed
The problem is caused by not testing for a null callback interface before using
the callback interface in line 88 of ComponentDocumentProcessor.java. There
are also two other places in ComponentDocumentProcessor.java and
ComponentTypeDocumentProcessor.java where the callback interface is used
without ensuring that it is non-null.
Fixed under revision r951561 by adding the missing null tests.
