      @PowerNukkitOnly @Since("1.4.0.0-PN") public static int dynamic(int value)
      A way to tell the java compiler to do not replace the users of a public static final int constant with the value defined in it, forcing the JVM to get the value directly from the class, preventing binary incompatible changes.
      Parameters:
      value - The value to be assigned to the field.
      Returns:
      The same value that was passed as parameter
