_Release info: 1.9.6 available 22-Jul-2020_

AspectJ 1.9.6 supports Java14. Java14 introduces records, but you must
activate support for that via an `--enable-preview` flag when using the
compiler and attempting to run the resultant classes: Here is `Code.java`:

[source, java]
....
public record Person(String firstName, String lastName, int age) {}

public class UsingPersonRecord {
  public static void main(String[] argv) {
    Person p = new Person("A","B",99);
    System.out.println(p);
    System.out.println(p.firstName());
  }
}

public aspect TraceRecordComponents {
  before(): execution(public * *()) {
    System.out.println(thisJoinPointStaticPart);
  }
}
....

Compile it with:

[source, text]
....
$ ajc --enable-preview -14 Person.java UsingPersonRecord.java TraceRecordComponents.java
....

Now run it:

[source, text]
....
$ java --enable-preview UsingPersonRecord
execution(String Person.toString())
Person[firstName=A, lastName=B, age=99]
execution(String Person.firstName())
A
....
