RFR: 8314275: Incorrect stepping in switch

[Aggelos Biboudis]

In code like the one below, the observable effect was that if the user debugs the following method, `multiply` called with `1`, the debugger steps from line 4 to line 6 (instead of 7) giving the impression that line 6 is going to be executed. The reason is that the `LineNumberTable` did not include an entry at the end of the `switch` mapping the statement that follows, to bytecode.


1 private static double multiply(Integer i) { 
2   double cr = 15;                              
3    cr = switch (i) {                            
4        case 1 -> cr * 1;                       
5        case 2 -> cr * 2;                      
6        default -> cr * 4;                     
7    };                                           
8    return cr;                              
9 }
