CodeToJoy: An open-source project surprised industry insiders today by announcing an implementation of the Java programming language on the JVM.
The language, dubbed jJava, reflects the current trend for using the JVM as a systems platform for various languages.
Bruce Eckel: Would it make sense to create a "Java 3K" (playing off of Python 3000, the name given by Guido Van Rossum to the once far-off, backwards-incompatible, fixed-up version of Python which is now going to appear sometime later this year)? A new version of Java that still runs on the JVM and has syntactic similarity with old Java, but is not hobbled with any kind of backward compatibility issues, so it can have real generics, closures, get rid of primitives, etc. If a company didn't want to move to Java 3K -- the same company that probably hasn't upgraded to Java 5 -- then it continues working with what it already has. But programmers who are being held back by the old issues and old bad decisions made in old Java can easily move forward into Java 3K, with only a small learning curve and virtually no productivity shortfall.
