Replaced asserts with NullPointerException calls because outside of testing that would be more informative - i do not think many people running their applications with assertions in system libraries enabled; Added a code that will analyze the result of the getIcon and will fall back to the default icon for the file type retrieved from the ShellFolder; Added a test case made by Aleksei Ivanov.
