Kotlin

http://kotlinlang.org/
Kotlin is JVM language with transparent Java interop (in both directions). It's a lot more concise and expressive than Java, whilst simultaneously having a stricter type system. The neat thing about Kotlin is, it's developed by JetBrains so you get completely seamless integration with their refactoring IDE. Also there is a Java-to-Kotlin converter feature that lets you turn a Java file into a Kotlin file instantly, and you can convert a codebase on a class-by-class basis. So you can start using the features of the new language right away. Also, it runs on Java 6, so it's Android compatible.

Kotlin is JVM language

Java 6 gave me the runs.

Stopped reading there. A VM with no tail call optimization or generics is useless.

B-but stack traces....

will be more detailed than if you used a loop construct instead

Stack traces for what exactly?
Besides, it's faster to just garbage collect stack frames as necessary rather than munge the current stack frame. That way you also get stack frames when you want them.

garbage collect stack frames

Brilliant! Put the stack on the heap! Amazing idea!

Concise
Drastically reduce the amount of boilerplate code you need to write.

fun main(args: Array<String>)

It's easy to beb ``concise'' when you compare versus java

Nice bebs you have there

What don't you like in that syntax? Looks pretty concise to me. They did choose the right short reserved word fun, which puts them above a half of programming languages.

Forced type declarations do not a concise language make.
Also don't be that guy.

I don't like that semicolons are optional. Either take it away or enforce it as a rule.
