I am working with the IntelliJ Community Edition source code and was wondering if there is any clarification on the licnese of the icons in the community edition. It looks like everything is under the Apache 2.0 license, so I would assume that this includes all files including the icons in the distribution (except for the seperate libraries and licenses included). But icons under an Apache 2.0 license is not very common and there is no explicit indication of the license for the icons in the distribution or the FAQ.
What license are the icons in the IntelliJ Community Edition licensed under?
