>Description:
Running the test code produces the output "0" instead of the expected "01234".

The break statement exits both for-loops (not just the innermost one) if the (single statement) body of the outer for-loop is not enclosed in braces. Affects more deeply nested loops in the same way.
>How-To-Repeat:
Run the following test code:

public class Main {
    public static void main(String argv[]) {
      int i, j;
      for (i=0; i<5; i++)
          for (j=0; j<2; j++)
              {
                  if (j==1) break;
                  System.out.print(i);
              }
    }
}
