Enabling Tomcat NIO Connector with Grails 2.0

At dozens of different sources, even in Graeme Rocher’s corresponding Jira ticket, it says that you need to put grails.tomcat.nio=true into your Config.groovy file. I believed that, too, and it drove me nuts to see that the org.apache.coyote.http11.Http11NioProtocol class wasn’t even instantiated.
I had to review the commit logs to figure out that the property should actually be in the BuildConfig.groovy file.
Now I finally got the log messages that I expected to see…
| Loading Grails 2.0.0
| Configuring classpath.
| Environment set to development.....
| Packaging Grails application.....
| Running Grails application
| Enabling Tomcat NIO connector
http11.Http11NioProtocol Initializing ProtocolHandler ["http-nio-8080"]
| Server running. Browse to http://localhost:8080/...
