How to disable "constant folding" in java compilation with javac?

Question

I have the following Java code:

public class App{
  public int sum(){
    return (1 + 2) + (3 + 4);
  }
}

After compiling it using javac App.java and inspecting the bytecode with javap -v App, I noticed that the method sum is optimized:

0: bipush        10
2: ireturn

It seems that javac performed constant folding. Is there a way to disable this behavior by default? I'm aiming to obtain verbose bytecode, resembling the following:

iconst_1
iconst_2
iadd
iconst_3
iconst_4
iadd
iadd
ireturn

Any insights or suggestions on how to achieve this would be greatly appreciated.
