My Eclipse javadoc view has a black background which makes it look terrible and partly unreadable (e.g. links are dark blue on black). Even worse, the javadoc popup has black background, too. I can't find the corresponding setting.
The answer by Sumit Singh showed me how to change the background for the javadoc view. However, I still see no way how to change the foreground. Even worse, the javadoc popup background color didn't change.
I don't think it's caused by a plugin, as it happens with a fresh install, too. This happens on Ubuntu 10.4. In Windows the colors can't be changed either, but there are fine.
