19  * This subclass of XFileOutputStream overwrites the constructors which otherwise will fail if:
20  * 
21  *     - The protocol used is a NFS URL and the path specified is mounted from another server
22  *     OR
23  *     - The path contains some escape codes and special characters that must be preserved.
24  * 
25  * Inside the constructors we first determine if the path is local to the JVM server; if so,
26  * then we replace special characters in the path with its respective escape code.
