Just tried IntelliJ IDEA 7.0.3 under the update N JDK (build 1.6.0_10-beta-b13) which appears to recognize my active LCD cleartype setting under Windows XP and enables the Java 6.0 subpixel antialiasing by default. It works pretty well for the menus and and stuff except I've noticed a number of controls and dialogs under IDEA don't antialias (run config chooser on menu bar) which leads to a somewhat scruffy inconsistent appearance.
The worst offender however is the actual editor. If I change to what should be a nice cleartype programming font like Consolas it looks really poor as it doesn't seem to share the same JVM subpixel aliasing setting. Under Apperances I can turn on antialiasing - but this appears to be the old style Graphics2D aatext antialiasing - not the 'improved' subpixel one? If I change the font in say Netbeans 6.0 to match the same Consolas family and size in IDEA, Netbeans looks much better for some reason?
This Appearances antialiasing setting also makes IDEA chug a bit.
In any case setting antialiasing in the editor doesn't appear to be shared by the editors completion popups, tool tips, intentions and the like - which use the editor font but without antialiasing - which in the case of most cleartype/truetype fonts reverts to unreadable spider scrawl?
Is improved font rendering (and consistency) on the roadmap somewhere?
