Thanks Ryan for creating a Bugzilla acount for me. Does creating an
attachement & submiting is all I have to do for sending new patches?
still now I dont have a clear picture of whats happening with
Bugzilla...what is this Bugzilla? & why does the patches sent are
considered as BUGS!!
Thanks & Regards
Praveen

Praveen,
I need you to go to this website:
http://issues.apache.org/bugzilla/createaccount.cgi and create an apache
bugzilla account, then I want you to go here:
http://issues.apache.org/bugzilla/createattachment.cgi?id=21325 and upload
Ffn.java and FontTable.java. Here is the issue I created for you:
http://issues.apache.org/bugzilla/show_bug.cgi?id=21325
