Java is battle-hardened and has seen almost every situation in the business programming. Go has miles to go before it can even be eligible to be compared to Java in terms of productivity and maintainability.

Fair enough about having to install a JVM separately. In my experience, it isn't a huge deal, but it's certainly a nonzero-sized deal.

But the classpath and jars? Write your application, 'gradle distZip', copy zip to target and unzip, invoke the launch script Gradle generated, done.

And if you can't be bothered to unzip, there's: https://github.com/pivotal/executable-dist-plugin

I agree with the classpath issue and hopefully it will be fix in Java 9. Separate jvm install? Why? JVM is backwards compatibility.

Those that develop non server apps since Java is a general-purpose language.

So you surely should be aware of the existing options to compile Java to native code, just like Go.
