Task: Signal an error for output on the standard output channel System.out.

We typically use the idiom System.out.println() for one-off debugging traces. It's a common mistake to leave these in your system far longer than is necessary. Create an aspect with the implementation given below to signal an error at compile time if this mistake is made.

package answers;
 
aspect Answer1 {
  declare error:
    get(java.io.PrintStream System.out) && within(figures..*):
      "Illegal access to System.out";
}

When you use this on the given system, you'll find one incorrect trace in SlothfulPoint.

Comment out the offending output line and continue with Exercise 2.
