Must Java development be so slow?

Starting a new VM each time an application is executed, forces numerous classes to be loaded multiple times. This overhead significantly slows down the development of Java software. So don't do it! We plan to eliminate these bottlenecks with an open Java environment where only one VM hosts all applications and classes are loaded only once. Furthermore we want to add a powerful textual user interface that allows command execution at a mouse-click in any text, supports literate programming, and thus highly enhances Java programming, development and maintenance of Java software.
