This is found in 2.1.30, however, the bug exists also in 2.2.0-RC1 even though the 'FileHandler' class has been changed. If we trace back the method ('getReplaceCollection(..)') from the stacktrace in both versions, the implementation remained same, hence, prone to 'ConcurrentModificationException'
