/**
 * Multiple users can get an upgradeable read lock on a file, but only one user
 * at a time can expand its read lock for a one-time write. As part of the
 * contract, the user who wants to rewrite the file must read it first. While at
 * least one user has an extensible read lock on a URI, no user can get
 * exclusive access to the URI. If he tries, he gets back the names of the lock
 * owners./*  w  w w.  j  av a2 s . c om*/
