I'm new to STS (coming from IntelliJ). I wanted a dark theme, so I installed Eclipse Color Themes plugin and applied a theme (Obsidian). It looks great with JSP, XML, HTML, JavaScript, properties files... etc.
But, when I open up a Java file I get a white background. Every other color is correctly changed (and largely unreadable on a white background).
It looks like this (cropped screenshot): http://i.imgur.com/Arry0Zz.png
The dark color on the left is defined in General --> Editors --> Text Editors: Background color
Searching "background" in the preferences, I cannot find any other place where background colors are defined for Java files.
I'm using Spring Tool Suite version 3.3.0.RELEASE. I also opened Eclipse Juno and it does the same thing.
