      Description

        In the example

        public class T {
          public static void main(String[] args) {
            System.out.println("\u005C\\u005D");
          }
        }

        The leading \u005C, equivalent to a backslash, should escape the following backslash and the output should be "\]". This was broken by JDK-8254073 (and subsequent patches) in JDK 16. JDK 16 generates an 'invalid escape' error.
