There is nothing missing. Java is backward compatible. – Mirek Pluta Nov 28 '21 at 08:14

See https://javaalmanac.io/jdk/17/apidiff/11/ In addition, when using reflection, Java 17 is more restrictive than Java 16 which is more restrictive than Java 15. – howlger Nov 28 '21 at 09:05

4@MirekPluta Unfortunately, this is no longer true since Java 9. A couple of things has been first deprecated and then removed from the system library, and newer versions have become more restrictive in terms of encapsulation. – howlger Nov 28 '21 at 09:08

The Java Version Almanac javaalmanac.io provides comparisons between different Java versions of the things that have been added or removed to the system library: see Java 17 vs. Java 11.
See also the release notes of removed features and options of Java 12 to 17:
- Java 12 - Removed Features and Options
- Java 13 - Removed Features and Options
- Java 14 - Removed Features and Options
- Java 15 - Removed Features and Options
- Java 16 - Removed Features and Options
- Java 17 - Removed Features and Options
Please also note the Strongly Encapsulate JDK Internals (JEP 396 and JEP 403): when using reflection, Java 17 is more restrictive than Java 11.
