On second thought, perhaps the 16 pixels Table.rowHeight is the correct approach.
And scaling up fonts to be a lot larger (as it happens in Win L&F) is what's wrong.

Because it violates write once, run anywhere.

On OS X you guys have been struggling to implement MultiResolutionImages and the like, so that if the physical display resolution is high, Java can automatically render a high resolution version of a given image. In the same spirit the L&F font sizes aren't suddenly changed, but instead they are rendered with greater detail. Because we use a virtual desktop resolution.

Now, if on Windows with Windows L&F suddenly all fonts are a lot larger, but images are still the same size (status quo) and in relation to labels way too small, things look out of proportion, layouts are broken.

The OS X solution allows for seamless migration, even if the programmer does not supply MultiResolutionImages. The current (1.7.0_45) Windows L&F does not allow this.

And regardless which approach is better: Shouldn't both L&Fs use the same approach?!

If you agree and have access to the Oracle bug database, please add this opinion as a comment (Oracle bug id 9008405). Or better—talk to the guys in charge of Windows L&F.

Thanks,
