FileSystem.getSize() should support 'unknown' length
----------------------------------------------------

                 Key: JBVFS-162
                 URL: https://jira.jboss.org/browse/JBVFS-162
             Project: JBoss VFS
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
            Reporter: Aslak Knutsen
            Assignee: John Bailey

When working with a Stream based FileSystem the size of the Stream could be unknown until streamed. FileSystem.getSize() forces writing the data to local disk to figure out the size (or stream it to '/dev/null' ).

FileSystem.getSize() supports a return type of '0L' to indicate a 'directory'. In the same fashion, it could match up with e.g. URLConnection.getContentLength() and support '-1L' to indicate a 'unknown size'.
