conclusion (forums.oracle.com/thread/2573652 similair as many his post there, nothing special)
- not true that Java, nor Nimbus bug, this bug in Font, you can to see that in Metal, Win, WinClassic and Nimbus Laf, OTF_Font missing 2pixels above glyph
. Windows . 
. Metal . 
. Nimbus . 
. Classic . 
WinXp on Java6
. versus . 
this code will help you to find difference(ies) between two fonts (and to report all diff's to author)
returns all available atributes from (java.awt.font.)TextAttribute for concrete Font
you can to get detailed properties from (almost) all TextAttributes
with output
java.awt.font.TextAttribute(family)
java.awt.font.TextAttribute(weight)
java.awt.font.TextAttribute(width)
java.awt.font.TextAttribute(posture)
java.awt.font.TextAttribute(size)
