Swing JEditorPane CSS capabilities
I am displaying HTML content inside a Swing JEditorPane. To change the default look of the HTML i am using a CSS style sheet. This works great. My problem is only that the JEditorPane does not support the full CSS specification. Is there a list of CSS features the JEditorPane supports?

Java has had a relatively poor record with regard to HTML/CSS support. The comment in the docs highlighted by trashgod have been promising improvements for years. Around about the time when JavaFX was being released there was talk of an official JWebPane which would allow Java developers access to the webkit engine, as used in Safari and Chrome. However, it never materialised.
The only advice I can offer is to look at alternative HTML/CSS renders for Java. One I'm often recommending is the xhtmlrenderer project. Development has slowed down as it generally maintains the existing version with the occasional bugfix. It targets CSS2.1, which is often more than adequate; although perhaps it'll move into CSS when the standard is actually finalised.
