Go ahead and integrate this issue after you get the necessary reviews. I think it is ok if it is using "Generic" as long as we have a plan to address that in a follow-up issue and add it as a standard name, or revert to something else if we decide differently.

Thanks, we appreciate this flexibility. My understanding is that we are now waiting for @driverkt's review, unless someone wants to make any other comment in this PR.

> Second, I would like to expand the scope of the new issue to include other uses of "Generic", as it is also used by the KEM API when [decapsulating](https://github.com/openjdk/jdk/blob/59c2aff1edffb66762bbbe5e310913f87953be5b/src/java.base/share/classes/javax/crypto/KEM.java#L206). Weijun just opened [an issue](https://bugs.openjdk.org/browse/JDK-8346736) that will address that and I think we should address the PKCS11 "Generic" name at the same time - I also want to make sure we think this through a bit more. So I would dup JDK-8346720 to the issue Weijun created.

Makes sense. Let us know if you need our collaboration. For now, I closed [JDK-8346720](https://bugs.openjdk.org/browse/JDK-8346720) as a duplicate of [JDK-8346736](https://bugs.openjdk.org/browse/JDK-8346736).
