Interfaces

Interface	Description
io.netty.util.concurrent.AbstractEventExecutor.LazyRunnable	override SingleThreadEventExecutor.wakesUpForTask(java.lang.Runnable) to re-create this behaviour
io.netty.util.concurrent.SingleThreadEventExecutor.NonWakeupRunnable	override SingleThreadEventExecutor.wakesUpForTask(java.lang.Runnable) to re-create this behaviour
io.netty.util.ResourceLeak	please use ResourceLeakTracker as it may lead to false-positives.

Classes

Class	Description
io.netty.util.concurrent.PromiseAggregator	Use PromiseCombiner(EventExecutor). GenericFutureListener implementation which consolidates multiple Futures into one, by listening to individual Futures and producing an aggregated result (success/failure) when all Futures have completed.
io.netty.util.concurrent.UnaryPromiseNotifier	use PromiseNotifier.cascade(boolean, Future, Promise).
io.netty.util.DomainMappingBuilder	Use DomainWildcardMappingBuilder instead.
io.netty.util.DomainNameMapping	Use DomainWildcardMappingBuilder}
io.netty.util.DomainNameMappingBuilder	Use DomainWildcardMappingBuilder
io.netty.util.internal.ConcurrentSet	For removal in Netty 4.2. Please use ConcurrentHashMap#newKeySet() instead
io.netty.util.internal.IntegerHolder	For removal in netty 4.2
io.netty.util.internal.logging.CommonsLoggerFactory	Please use Log4J2LoggerFactory or Log4JLoggerFactory or Slf4JLoggerFactory.
io.netty.util.internal.ThreadLocalRandom
io.netty.util.ThreadDeathWatcher	will be removed in the next major release

Exceptions

Exceptions	Description
io.netty.util.ResourceLeakException	This class will be removed in the future version.
