JIT hotspot compiler

The Java JIT compiler compiles Java bytecode to native executable code during the runtime of your program. This increases the runtime of your program significantly. The JIT compiler uses runtime information to identify part in your application which are runtime intensive. These so-called “hot spots” are then translated native code. This is the reason why the JIT compiler is also called “Hot-spot” compiler.

JIT is store the original bytecode and the native code in memory because JIT can also decide that a certain compilation steps must be revised.
