So after spending 20-30 mins working out why Docky shows two Icons when I open Netbeans I found a bug on Launchpad.net

After reading through the comments I found the fix from one of the Docky Devs which is found here.
Docky fix for Netbeans issue
As I was on a roll I thought, why not contact Netbeans and ask them to add it to the installer, so five minutes later I had registered and after a search on the Bugzilla data base found that no one else had raised this bug I submitted it.

Let’s hope that I don’t get shot down for doing something wrong but at least I’ve made a start to improving my contributions to my use of Ubuntu.
Update : Spelling mistake, thanks Matt
