'switch' statement with too low of a branch density

Reports switch statements or expressions with a too low ratio of switch labels to executable statements.

Such switch statements may be confusing and should probably be refactored.

Example:

switch (i) { // one case and 5 executable statements -> 20% density
    case 1:
        System.out.println("1");
        System.out.println("2");
        System.out.println("3");
        System.out.println("4");
        System.out.println("5");
        break;
}

Use the Minimum density of branches field to specify the allowed ratio of the switch labels to executable statements.
