I have removed awt-dev and replaced it with the CORRECT 2d-dev list.
Please reply to this one .. to get awt-dev out of the loop.
I already have an open bug to upgrade harfbuzz I will be handling soon.
If the necessary changes are there we are all good.
We do not much like at all locally modifying sources we get from upstream.
It is a maintenance nightmare.
