 Languages for the Java VM
The goals of the transliteration are readability of the generated Java source code, easy integration and interfacing with native Java code, little or no user interaction during the transliteration process, good performance, and basic C++ support.
The resulting Java source code can then be compiled using any JDK 1.1+ compliant Java Compiler and will run on any JDK 1.1+ implementation of the Java Virtual Machine as either an applet or application depending upon how the program is invoked (applets are subject to applet security restrictions).
Java bytecode can be generated either through a script which drives the assembler package, or directly accessing the assembler package from java.

 LaTTe: A Fast and Efficient Java VM Just-in-Time Compiler
Recently, Java became a prominent language with a wide application spectrum, from embedded systems to enterprise servers.
The Java Virtual Machine (JVM), a software layer to execute Java bytecodes, while providing desirable features such as a "write-once, run anywhere model" for software developers, and security and portability for end-users, does not immediately lend itself to high performance.
Since the JIT compilation itself is part of the total execution time of a Java program, it must be fast and the benefit from compilation must outweigh the JIT compilation overhead.

You would basically invoke the Java Container application saying "launch this application with this VM" The VM container would check to see if the requested version is installed.
Rather than running the installation, the application being installed can drop the new VM into the Container with information saying not to mess with the default VM and not to set the new plugin as the default.
The VM could be separated out into core and external (like Javax was supposed to be) and only the core is installed by default.
