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 = "";
switch (m) {
case 0:
String b = "";
break;
default:
throw new Exception("Unknown ");
}
}
public static void main(String[] args) throws Exception {
new SwitchCompilerErr().switchTo();
}
}
---------- END SOURCE ----------
CUSTOMER SUBMITTED WORKAROUND :
inserting variable definition in between switch statements prevents this issue
