I remember that the official Microsoft JVM (which was quickly discontinued) used native Windows GUI controls to display the Java UI, and then later, the JVM on Mac OS X displayed Swing(?) apps with native controls. I thought it was all very neat, but against the interests of the companies.

Java applications on mac had a very uncanny way of showing native controls. It is a bit like Qt, it kind of looks like a knock-off - elements are out of alignment, weirdly sized and so on.
