[Amos Shi]

Backport of [JDK-8180266](https://bugs.openjdk.org/browse/JDK-8180266)

Unclean Backport:
- `test/jdk/sun/security/provider/KeyStore/DKSTest.java`
  - The `Copyright year` line basement are different, merged manually
  - This line does not affect application logic, so can be considered as `Clean` backport

Test Succeeded in local Dev Apple M1 Laptop
