/**
* Creates a new <tt>File</tt> instance by converting the given
* <tt>file:</tt> URI into an abstract pathname.
*
* <p> The exact form of a <tt>file:</tt> URI is system-dependent, hence
* the transformation performed by this constructor is also
* system-dependent.
*
* <p> For a given abstract pathname <i>f</i> it is guaranteed that
*
* <blockquote><tt>
* new File(</tt><i> f</i><tt>.{@link #toURI() toURI}()).equals(</tt><i> f</i><tt>.{@link #getAbsoluteFile() getAbsoluteFile}())
* </tt></blockquote>
*
* so long as the original abstract pathname, the URI, and the new abstract
* pathname are all created in (possibly different invocations of) the same
* Java virtual machine. This relationship typically does not hold,
* however, when a <tt>file:</tt> URI that is created in a virtual machine
* on one operating system is converted into an abstract pathname in a
* virtual machine on a different operating system.
*
* @param uri
* An absolute, hierarchical URI with a scheme equal to
* <tt>"file"</tt>, a non-empty path component, and undefined
* authority, query, and fragment components
