Refactored PKCS9Attribute to use a hash map instead of multiple arrays. The key for the hash map is an `ObjectIdentifier` and the values are a record `AttributeInfo` that stores the information previously contained in the arrays `PKCS9_VALUE_TAGS`, `VALUE_CLASSES`, and `SINGLE_VALUED`.
It seems as though we should be able to get rid of constants such as `EMAIL_ADDRESS_OID` since they aren't heavily used with the hash map approach, but since the values are public it might cause compatibility issues. Another question is how to handle `RSA DSI`, `S/MIME`, `Extended-certificate`, and `Issuer Serial Number` OIDs. The prior version threw an error but in this refactor they are treated as an "unknown OID" and only throw a debug warning. This was addressed in https://bugs.openjdk.org/browse/JDK-8011867 but prior to this refactor the aforementioned OIDs were treated differently than unknown OIDs. ------------- Commit messages: - refactored PKCSAttribute to use a hash map instead of multiple arrays Changes: https://git.openjdk.org/jdk/pull/17132/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=17132&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8265372 Stats: 245 lines in 1 file changed: 39 ins; 110 del; 96 mod Patch: https://git.openjdk.org/jdk/pull/17132.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/17132/head:pull/17132 PR: https://git.openjdk.org/jdk/pull/17132
