Saminda Wijeratne commented on AIRAVATA-229:
--------------------------------------------
Problem with shutdown hooks is that by the time it gets triggered all the
objects have being disposed from the environment. Therefore we cannot do
anything at this point....
However it is possible to capture when xbaya is closing (using window events)
to perform the above operations.
Committed revision 1400139.
