[jcifs] SMBFile hashcode bug

[James Nord]

Hi,

it seems to me at this late hour that the hashcode function of SmbFile 
ignores any authentication when calculating its hashcode.

Also some SMB implementations can be case sensitive so
smb://server/share/file may not equal smb://server/share/File

And shares?

    public int hashCode() {
        if( hash == 0 ) {
            try {
                hash = getAddress().hashCode();
            } catch( SmbException se ) {
            }
            if( port != 0 && port != 139 ) {
                hash += 65621 * port;
            }
            if( share != null ) {
                hash += 65521 * share.toUpperCase().hashCode();
                if( canonicalPath != null ) {
                    hash += 65521 * canonicalPath.toUpperCase().hashCode();
                }
            }
        }
        return hash;
    }
