REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
import java.util.Random;

public class SwitchCompilerErr {

private void switchTo() throws Exception {
int e = new Random().nextInt();
int m = new Random().nextInt();
switch (e) {
case 0:
String a = "";
break;
default:
throw new Exception("Unknown ");
}
// String z = "";

public static void main(String[] args) throws Exception {

---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
inserting variable definition in between switch statements prevents this issue
