No. It's not a bug. You are not implemented switch properly. It's fall through. You need to have break after each case.

For ex :

    switch (exc.getEvent()) {
    case EVENT_ONE :
    //once EVENT_ONE gets here;
    break;
    case EVENT_TWO : case EVENT_THREE :
   //it keeps going everywhere;
    break;
    case EVENT_FOUR :
   //and so on;
    break;

Here is the official doc for the same

Another point of interest is the break statement. Each break statement terminates the enclosing switch statement. Control flow continues with the first statement following the switch block. The break statements are necessary because without them, statements in switch blocks fall through: All statements after the matching case label are executed in sequence, regardless of the expression of subsequent case labels, until a break statement is encountered.
