Running Groovy with invokedynamic support
One of the biggest improvements introduced in Groovy 2.0 is the support for the invokedynamic instruction. The invokedynamic is a new JVM instruction available in Java 7, which allows easier implementation and promises increased speed and efficiency of dynamic languages (for example, Groovy).
Dynamic languages generate a bytecode that often necessitates a number of JVM method invocations to perform a single operation. Furthermore, reflection and dynamic proxies are used extensively, which comes with a costly performance toll. Also, the JIT (Just-In-Time) compiler that helps to improve the runtime performance of a JVM, cannot work its magic by applying optimization to the bytecode because it lacks information ...
