/**
* Gives the same basic functionality of File.exists but can be used to look for removable media
* without showing a system dialog if the media is not present. Workaround pulled from the <A
* HREF="http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4089199"> bug report</A> on
* bugs.sun.com. This bug was fixed in Java 6, and we can remove the workaround when we start
* requiring Java 6.
