CCE is thrown when trying to extract new method from part of case branch of
switch statement.

Steps to reproduce:
1) open some class and write this code:
        int x = 1;
        switch (x) {
            case 1: 
                |>System.out.println("a");
                System.out.println("b");<|
                break;
        }
2) select both println commands (as marked with '|>' and '<|' symbols)
3) call Extract method
-> CCE thrown

In step 2) it is important to select both lines otherwise it works
