In the Java VM specification, switch/case instructions can be compiled/encoded into bytecodes in two alternative ways.
In the following example of Java code, what would be the most appropriate way to compile/encode the switch/case instruction into bytecodes.

switch (x) {
case 999: return 1;
case 1000: return 0;
case 1001: return 1;
default: return -1;
}

(select the option that best fits the question).
