I've tried searching for an exact duplicate of this
bug but couldn't find one. The closest report seems
to be 4140220. Maybe it's related.

When using Font("Dialog", Font.PLAIN, 11) as the font
in a JTextComponent, the text will not render properly
- it starts at the wrong position (one pixel to the left
of where it should be). This also has the effect that
the caret will appear "on top" of each character instead
of "just before" it. Other font sizes such as 10pt,
12pt or 13pt do not show this problem. See the
attached test case for a demonstration of the issue
(by the way, NetBeans, which also uses an 11pt font,
is affected too). Again, to clarify, this is not
about wide characters being clipped but the whole
text being somehow shifted one pixel to the left
(when compared to other font sizes).
