Idel Pivnitskiy dd026eb60a Fix NPE problems ... Motivation: Now Netty has a few problems with null values. Modifications: - Check File in DiskFileUpload.toString(). If File is null we will get NPE when calling toString() method. - Check Result<String> in MqttDecoder.decodeConnectionPayload(...). - Check Unsafe before calling unsafe.getClass() in PlatformDependent0 static block. - Removed unnecessary null check in WebSocket08FrameEncoder.encode(...). Because msg.content() can not return null. - Removed unnecessary null checks in ConcurrentHashMapV8.removeTreeNode(TreeNode<K,V>). - Removed unnecessary null check in OioDatagramChannel.doReadMessages(List<Object>). Because tmpPacket.getSocketAddress() always returns new SocketAddress instance. - Removed unnecessary null check in OioServerSocketChannel.doReadMessages(List<Object>). Because socket.accept() always returns new Socket instance. - Pass Unpooled.buffer(0) instead of null inside CloseWebSocketFrame(boolean, int) constructor. If we will pass null we will get NPE in super class constructor. - Added throw new IllegalStateException in GlobalEventExecutor.awaitInactivity(long, TimeUnit) if it will be called before GlobalEventExecutor.execute(Runnable). Because now we will get NPE. IllegalStateException will be better in this case. - Fixed null check in OpenSslServerContext.setTicketKeys(byte[]). Now we throw new NPE if byte[] is not null. Result: Added new null checks when it is necessary, removed unnecessary null checks and fixed some NPE problems.		2014-07-20 12:56:21 +02:00
