Loop executes zero or billions of times

Reports loops that cannot be completed without an index overflow or loops that don't loop at all. It usually happens because of a mistake in the update operation.

Example:

void foo(int s) {
  for (int i = s; i > 12; i++) { // i-- should be here
    System.out.println(i);
  }
}
