Java cannot be written without a code completion IDE (unless you are a masochist), python OTOH, does not have such limitations. Forget runtime performance, coding in Java sucks more than any other language in my 'limited' experience. com.java.cookie.JarFactoryMakingMonkeyWrenchFrenchFriedOnionTrainPlaneJaneSpain.... you get the point. Want to counter that? Show me tight, non-verbose, working code in Java. At the end of the day, what you call a 'pissing contest' is rooted in a figment of truth and reality.

Please take a look at the Apache Lucene and Tinkerpop Blueprints codebase that will soundly meet all your parameters.
