So why did you remove the check for null ?

Hi All,
Please review a fix for an issue where it is seen that "Print-To-File"
option is enabled even for flavors that do not support Destination
attribute
even though isAttributeValueSupported for that flavor returns false.
Bug: https://bugs.openjdk.java.net/browse/JDK-5049012
webrev: http://cr.openjdk.java.net/~psadhukhan/5049012/webrev.00/
The reason for this behaviour is in Print Dialog code, the validation
is done against isAttributeCategorySupported() which still returns
true because Pageable and Printable supports it
and therefore the "Print-to-File" option gets enabled.
But print dialog is shown specific to a doc flavor and a print service
(selected one) and hence must validate the attribute against the
chosen doc flavor.
So, the proposed fix checks the attributevalue is supported or not for
that flavor to determine if we need to enable "Print-to-File" option
in print dialog.
