java.net.UnknownHostException on OSX and Java 7

[Oliver Schrenk]

Hi,

Just and FYI for all users on OSX using Java 7. I was trying to start a TCP Server from within an application using

Server.createTcpServer().start();

and got

org.h2.jdbc.JdbcSQLException: "java.net.UnknownHostException: MacBook: MacBook: nodename nor servname provided, or not known"

IO Exception: "java.net.UnknownHostException: MacBook: MacBook: nodename nor servname provided, or not known" [90028-170]

This is a bug in the JDK 7 for OSX as noted in [1] (login required) and more recently on [2]

The workaround is to add the name of the machine to your `/etc/hosts` file, in my case

127.0.0.1 MacBook

Best regards

Oliver Schrenk

Thank you Oliver so much.

I had this problem and could not figure out why.
