Knut Anders Hatlen updated DERBY-6296:
--------------------------------------

    Attachment: d6296-1a.diff

Attaching d6296-1a.diff which changes PropertyUtil as suggested.

Mostly minor changes. In sortProperties(), the patch removes a good chunk of code, as we can now just call toArray() on the set instead of walking the Enumeration and managing the space in the resulting array manually.

> PropertyUtil should use Properties.stringPropertyNames() (new method in Java 6) instead of Properties.propertyNames() since a Set<String> view of the property names is easier to work with than an Enumeration<?>. The Set<String> view can be used with for-each loops and many of the helper methods in the standard library.
