Nice. It may be the best way to organize project this large. I know this is maven thing and once using everyone's favorite Intellij IDEA it should not matter but I personally find ~1000 directories for ~4000 files a kind of Javasim.
I believe its more because companies that have "enterprise apps" culture embraced java more, rather than it being the fault of Java itself. I've seen first-hand when these companies have "enterprisified" C++, C# and heck, even PHP
I do think Java the language has a long way to go, but it is catching up a bit. I see it as the least common denominator language for most companies. Large open source java projects have been successful (everything on hadoop, hbase, cassandra etc) and a lot less enterprisey.
