fix a potential ByteBuf leak in HttpProxyHandler. (#10130)
Motivation:

An exception may occur between ByteBuf's allocation and release. For example:
```java
java.lang.OutOfMemoryError: Java heap space
	at java.lang.String.<init>(String.java:325)
	at io.netty.buffer.ByteBufUtil.decodeString(ByteBufUtil.java:838)
	at io.netty.buffer.AbstractByteBuf.toString(AbstractByteBuf.java:1247)
	at io.netty.buffer.AbstractByteBuf.toString(AbstractByteBuf.java:1242)
	at io.netty.handler.proxy.HttpProxyHandler.<init>(HttpProxyHandler.java:105)
	at io.netty.handler.proxy.HttpProxyHandler.<init>(HttpProxyHandler.java:90)
	at io.netty.handler.proxy.HttpProxyHandler.<init>(HttpProxyHandler.java:85)
```
It may cause the ByteBuf variable authz and authzBase64's leak.

Modification:

Release the ByteBuf in a finally block as soon as possible.

Result:

Fix a potential ByteBuf leak.

Netty Project

Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients.

How to build

For the detailed information about building and developing Netty, please visit the developer guide. This page only gives very basic information.

You require the following to build Netty:

Note that this is build-time requirement. JDK 5 (for 3.x) or 6 (for 4.0+) is enough to run your Netty-based application.

Branches to look

Development of all versions takes place in each branch whose name is identical to <majorVersion>.<minorVersion>. For example, the development of 3.9 and 4.0 resides in the branch '3.9' and the branch '4.0' respectively.

Usage with JDK 9

Netty can be used in modular JDK9 applications as a collection of automatic modules. The module names follow the reverse-DNS style, and are derived from subproject names rather than root packages due to historical reasons. They are listed below:

  • io.netty.all
  • io.netty.buffer
  • io.netty.codec
  • io.netty.codec.dns
  • io.netty.codec.haproxy
  • io.netty.codec.http
  • io.netty.codec.http2
  • io.netty.codec.memcache
  • io.netty.codec.mqtt
  • io.netty.codec.redis
  • io.netty.codec.smtp
  • io.netty.codec.socks
  • io.netty.codec.stomp
  • io.netty.codec.xml
  • io.netty.common
  • io.netty.handler
  • io.netty.handler.proxy
  • io.netty.resolver
  • io.netty.resolver.dns
  • io.netty.transport
  • io.netty.transport.epoll (native omitted - reserved keyword in Java)
  • io.netty.transport.kqueue (native omitted - reserved keyword in Java)
  • io.netty.transport.unix.common (native omitted - reserved keyword in Java)
  • io.netty.transport.rxtx
  • io.netty.transport.sctp
  • io.netty.transport.udt

Automatic modules do not provide any means to declare dependencies, so you need to list each used module separately in your module-info file.
