SUN обещает обновить JVM изнутри для лучшей поддержки нетипизированных (скриптовых) языков:
"There is growing interest in running a variety of programming languages on the the Java platform, and consequently, on the Java virtual machine (JVM). This interest is increasingly focused on dynamically typed languages, in particular scripting languages. To make it easier to produce performant, high quality implementations of such languages, we propose to add support at the virtual machine level. Specifically, we seek to add a new JVM instruction, invokedynamic, designed to support the implementation of dynamically typed object oriented languages. We will also investigate support for hotswapping, the capability to modify the structure of classes at run time."
