commit 24d9e5128c8d823a86d1ccc011f6d058e414c709 Author: Karsten Loesing karsten.loesing@gmx.net Date: Wed Feb 25 11:58:09 2015 +0100

Use Apache Common Lang's StringUtils.replace correctly.

When we switched from String.replaceAll to StringUtils.replaceEach for performance reasons, we forgot to change the passed regular expression into a simple string. That's why some of our replacements didn't work out as expected.
