Beyond JVM: How the platform is evolving for new languages and features

The JVM has traditionally hosted many languages, but only those closest to Java itself got the full optimization treatment. Those days are changing rapidly with new JVM features like invokedynamic and lambda, and with the rise of new frameworks like Truffle and Nashorn. In this talk we'll explore what it takes to optimize more exotic languages like JavaScript and Ruby and see how the JVM is evolving to do a better job. We'll see how projects like JRuby and Nashorn are trying to work around gaps in the JVM's optimizer. We'll see how JRuby+Truffle routes around the JVM to achieve blistering fast performance. And we'll look at upcoming projects on the JVM that will make language-building even easier.
