Can you confirm this?
I am using Java SE 7 U 25 on Windows 7 Pro 64bit
When I switch between the otf and the ttf version of the same font (Source Sand Pro by Adobe) then I see some differences (see the space above the "O")
But why? Is this a bug? My Java app uses the Swing L&F Nimbus
I know. But I have tried it also with another font - same problem
There is indeed a bug with the display of ttf/otf fonts in Java / Swing
