Bug 77537 [preferences] Preview window in Preferences->Java->Properties File Editor displays incorrect background color
The properties file editor seems to inherit its background color from the setting in Preferences->Java->Editor->Syntax. However, the preview window in Preferences->Java->Properties File Editor always displays a white background.
