Presented at JAX London 2013
Ever since Java’s inception, in 1995, people have been compiling languages that aren’t Java to bytecode and deploying them on the JVM. Lately we are seeing an explosion in JVM languages. This is partly, but not only, because of Java 7, the first JVM to ship with invokedynamic, which is a quantum leap in polyglot runtime implementation. This session explains why emerging language implementations are becoming more common and more feasible to implement on the JVM with satisfactory performance.
