When revieweing PR#1237 I've encountered some bugs - exhibited in the following example. Tested on master branch.
{code:java}
package javaapplication1;

/**
 *
 * @author sdedic
 */
public class JavaApplication1 {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        // TODO code application logic here
        int a = 0;
        int b = 2;
    }
    
    int f1(String p) {
        int a = 0;
        int b = 2;
        int r = 5;
        switch (p) {
            case "a": {
                if (a == 0) {
                    // this break will be removed, so on a == 0, r will not remain 5
                    break;
                }
                r = 1;
                break;
            } 
            
            case "b": r = 2; break;
        }
    }
    
    int f4(String p) {
        int a = 0;
        int b = 2;
        int r;
        
        switch (p) {  
            case "a": 
                return 1;
            // this will turn into 'return 2', but original code returns 2+2.
            case "b": r = 2; break;
            default: r = 3; break;
        };
               
        return r + 2;
    }
}
{code}
