Why can't JIT compilers be used to create binaries?

JIT compilers are used to convert java byte code into native machine language. And, as far as I know, there is no program that can directly convert java-byte code to a binary file, such as .exe files. So why can't JIT compilers be used to create binary code from byte code?

The JIT compiler compiles code dynamically.

  • It generates different code for different processor options.
  • It generates different code for different memory models, for example. For a 64-bit JVM, if the maximum heap size is <4 GB, 24 GB, 32 GB or more, you will create different codes in each case.

The IBM Java Runtime is able to store dynamic bytecode results for compiling native code in its shared data cache and share it between the JVM ( prooflink ).
