Hey,

Netty 4.2.13 introduced a breaking change by removing a public constructor.

• 4.2.12: https://github.com/netty/netty/blob/netty-4.2.12.Final/handler-proxy/src/main/java/io/netty/handler/proxy/HttpProxyHandler.java#L84-L86
• 4.2.13: https://github.com/netty/netty/blob/netty-4.2.13.Final/handler-proxy/src/main/java/io/netty/handler/proxy/HttpProxyHandler.java#L113-L118

I can live with it but I thought I would let you know.

Cheers
