[String templates] Internal compiler error: java.lang.NegativeArraySizeException: -3 at Scanner.getCurrentTokenInRange(Scanner.java:525)

While playing around with the example in #1719 I ended up with a
NegativeArraySizeException when compiling this snippet:

public class X {
  public static void main(String[] args) {
    String firstName = "Bill", lastName = "Duck";
    System.out.println(STR."\{firstName} \{lastName}");

    String title = "My Web Page";

    String html = STR."""
        </head>
      """;
    System.out.println(html);
  }
}

This compiles fine:

public class X {
  public static void main(String[] args) {
    String firstName = "Bill", lastName = "Duck";
    System.out.println(STR."\{firstName} \{lastName}");

    String title = "My Web Page";

    String html = STR."""
    //      <title>\{title}</title>
        </head>
      """;
    System.out.println(html);
  }
}

Deleting the line // <title>\{title}</title> causes the crash

Crash also with:

public class X {
  public static void main(String[] args) {
    String firstName = "Bill", lastName = "Duck";
    System.out.println(STR."\{firstName} \{lastName}");

    String title = "My Web Page";

    String html = STR."""
    
      """;
    System.out.println(html);
  }
}

Pull #1730 took care of this. Closing.
