Idel Pivnitskiy 6860019f41 Fix NPE problems ... Motivation: Now Netty has a few problems with null values. Modifications: - Check HAProxyProxiedProtocol in HAProxyMessage constructor and throw NPE if it is null. If HAProxyProxiedProtocol is null we will set AddressFamily as null. So we will get NPE inside checkAddress(String, AddressFamily) and it won't be easy to understand why addrFamily is null. - Check File in DiskFileUpload.toString(). If File is null we will get NPE when calling toString() method. - Check Result<String> in MqttDecoder.decodeConnectionPayload(...). If !mqttConnectVariableHeader.isWillFlag() || !mqttConnectVariableHeader.hasUserName() || !mqttConnectVariableHeader.hasPassword() we will get NPE when we will try to create new instance of MqttConnectPayload. - 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 check in DefaultStompFrame(StompCommand) constructor. Because we have this check in the super class. - 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 12:55:08 +02:00
