Norman Maurer 34fdc7a33e Skip invalid hostnames when construct default dns servers to use.
Motivation:

When the hostname portion can not be extracted we should just skip the server as otherwise we will produce and exception when trying to create the InetSocketAddress.

This was happing when trying to run the test-suite on a system and using java7:

java.lang.IllegalArgumentException: hostname can't be null
	at java.net.InetSocketAddress.checkHost(InetSocketAddress.java:149)
	at java.net.InetSocketAddress.<init>(InetSocketAddress.java:216)
	at io.netty.util.internal.SocketUtils$10.run(SocketUtils.java:171)
	at io.netty.util.internal.SocketUtils$10.run(SocketUtils.java:168)
	at java.security.AccessController.doPrivileged(Native Method)
	at io.netty.util.internal.SocketUtils.socketAddress(SocketUtils.java:168)
	at io.netty.resolver.dns.DefaultDnsServerAddressStreamProvider.<clinit>(DefaultDnsServerAddressStreamProvider.java:74)
	at io.netty.resolver.dns.DnsServerAddressesTest.testDefaultAddresses(DnsServerAddressesTest.java:39)

Modifications:

Skip if hostname can not be extracted.

Result:

No more java.lang.ExceptionInInitializerError.

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.
