Fonts won't be fixed in Java 6. I have a bug open with Sun. Swing
fonts are rendered with a pure-Java routine. True GTK+ fonts are
rendered with pango. Java 7 will delegate to pango for font rendering
In the mean time, they have improved the rendering of Java 6 fonts to
be much closer to their native counterparts. They are off, but I
personally doubt that the lay-user would notice at all.

I don't mind SWT's API or the architecture per se. What I don't like
about it is, 1) it doesn't come with the JDK by default (so you get an
extra 3 - 4MB to download with your app), and SWT doesn't have a sweet
GUI builder like the one that exists for Swing in NetBeans. Eclipse
has an SWT GUI builder plugin, but it is pretty sorry compared to
Other than fonts did you find anything else in the GTK emulation that was off?
