I thought the example was a little terse, he didn't even bother to include an XML configuration file for his IOC container, or a bunch of maven dreck to import a couple libraries. He also forgot to name the file correctly so it might not even compile. As well the batch file/shell script so it will actually execute and pass a bunch of arcane -XMemory flags to java.
Actually it was designed to run on washing machines, refocused to work for browser applets, and then refocused again to deal with massive enterprise apps. I'm not sure it was ever suited to any of those tasks -- it's merely has a good enough cross section of features. One only has to look over at what Microsoft has done with C# to see that Java could be significantly less verbose.
