[undertow-dev] ClosedChannelException

I seem to be experiencing a lot of: [XNIO-1 task-40] ERROR i.y.E.defaultHandler.???:23 - java.nio.channels.ClosedChannelException at io.undertow.protocols.ssl.SslConduit.write(SslConduit.java:369) at org.xnio.conduits.ConduitStreamSinkChannel.write(ConduitStreamSinkChannel.java:150) at org.xnio.http.HttpUpgrade$HttpUpgradeState$StringWriteListener.handleEvent(HttpUpgrade.java:385) at org.xnio.http.HttpUpgrade$HttpUpgradeState$StringWriteListener.handleEvent(HttpUpgrade.java:372) at org.xnio.ChannelListeners.invokeChannelListener(ChannelListeners.java:92) at org.xnio.conduits.WriteReadyHandler$ChannelListenerHandler.writeReady(WriteReadyHandler.java:65) at io.undertow.protocols.ssl.SslConduit$SslWriteReadyHandler.writeReady(SslConduit.java:1225) at io.undertow.protocols.ssl.SslConduit$3.run(SslConduit.java:275) at org.xnio.nio.WorkerThread.safeRun(WorkerThread.java:580) at org.xnio.nio.WorkerThread.run(WorkerThread.java:464) I'm not positive this is connected to my update to 1.4.12.Final, but I wanted to check to see if this is something anyone else is seeing? It's likely it's related to my code, although I have no idea what I would have changed to cause this.
