The question is where the native rasterisation is used vs where
the Java rasteriser is used. We don't use LCD rasterisation of
either flavour in such cases.
There are also limitations to where Microsoft can or do apply cleartype.
I've seen it in the distant past although I can't say for certain if
it was the circumstances described/discussed here (transforms):

..
and here (intermediate surfaces) in a posting by a MS WPF engineer :

The sole exception to this is the glyphs from fonts
that are in the
jre/lib/fonts directory - ie the fonts
that ship with Java. For the Windows JRE this means
Lucida Sans Regular.
There is another, much bigger exception - painting texts on translucent surfaces
(when the current SrcOver composite has alpha < 1.0) uses the bundled
rasterizer, which is inferior as far as Segoe UI font (default Vista) is concerned.
