With the addition of support for JSR 292 in JDK 7, dynamically typed languages should run faster in the JVM than they do today. A key part of this support is the addition of a new Java bytecode, invokedynamic, for method invocation, and an accompanying linkage mechanism that involves a new construct called a method handle. These features enable implementers of compilers for dynamically typed languages, that is, the people who develop compilers for languages such as JRuby and Jython, to generate bytecode that runs extremely fast in the JVM.
...
A method handle is a simple object of type java.dyn.MethodHandle that contains an anonymous reference to a JVM method. A method handle is callable just like a named reference to a method. What makes it unique, however, is that it is accessed through a pointer structure, as opposed to a linked name.
