jdk.jpackage.test.CannedFormattedString record class [1] has the "args" parameter of type Object[]. This makes the default equals() method work unexpectedly:

```
var date = new Date();

CannedFormattedString strA = JPackageStringBundle.MAIN.cannedFormattedString("foo", "param.copyright.default", date);

CannedFormattedString strB = JPackageStringBundle.MAIN.cannedFormattedString("foo", "param.copyright.default", date);

assertEquals(strA, strB); // assertion fails
```

Replace the type of the "args" parameter from Object[] to List<Object>.
