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
