Dmitriy Dumanskiy 45c0ea543f Java 8 migration. Replace netty ConcurrentSet with Java KeySet. (#8745) ... Motivation: The concurrent set is present in Java 8 and above so we can use it instead of own implementation. Modification: io.netty.utik.internal.ConcurrentSet replaced with ConcurrentHashMap.newKeySet(). Result: Less code to maintain.		2019-01-22 10:40:40 +01:00
