- This is the legacy pattern, where there is only one instance of the Velocity engine in the JVM (or web application, depending) that is shared by all.
- If your web application is a quality one, the Private JVM can be run for long periods of time, providing the best performance.
- Compiled bytecode is a form of optimized machine code for the JVM; the interpreter is an implementation of the JVM.
- The byte code generated by the compiler can be interpreted by any JVM of any machine.
- There is no limitation as to where these memory areas must actually exist, making the JVM more portable and secure.
- The difference is that Java bytecode can also be interpreted as well as compiled, but the JVM supports only Java, not multiple programming languages.
- It also promises, in the future, to provide universal debugging support for most programming languages for the JVM. Published May.

- Instead, a special computer program called the JVM, or Java Virtual Machine, is run by the operating system, which in turn runs the Java program.
- Each platform has installed a JVM that is specific to its operating system.
- JVM actually uses operating system and machine instructions to carry out the instructions it has been given.
