Tony McCrary continues his awesome icon contributions.
This time he managed to re-create the JDT icon set so that the JDT icon look good on a dark background. This work started in January 2014 (!!!) and as the JDT developer are under a high pressure, Tony even generated a gallery to compare the old gif and the new png icons to make the review easier for them.
On the left you see the old gif icons, the right are the new png icons.
See JDT icon work Bug for details.
Many thanks from me personally and the platform.ui team to Tony.
