I added @since tags for methods/constructors that do not match the @since of the enclosing class.

The write method already existed in PrintStream in earlier versions and instances of it could always call this method, since it extends FilterOutputStream which has the method.

for MappedByteBuffer slice() and MappedByteBuffer slice(int index, int length), the return type changed from ByteBuffer to MappedByteBuffer. And the checker tool differentiates between them because of that.

This is similar to #18032 and #18373

For context, I am writing tests to check for accurate use of @since tags in documentation comments in source code.
We're following these rules for now:

Rule 1: Introduction of New Elements

  • If an element is new in JDK N, with no equivalent in JDK N-1, it must include @since N.
    • Exception: Member elements (fields, methods, nested classes) may omit @since if their version matches the value specified for the enclosing class or interface.

Rule 2: Existing Elements in Subsequent JDK Versions

  • If an element exists in JDK N, with an equivalent in JDK N-1, it should not include @since N.

Rule 3: Handling Missing @since Tags in methods if there is no @since

  • When inspecting methods, prioritize the @since annotation of the supertype's overridden method.

  • If unavailable or if the enclosing class's @since is newer, use the enclosing element's @since.

    I.e. if A extends B, and we add a method to B in JDK N, and add an override of the method to A in JDK M (M > N), we will use N as the effective @since for the method.

Hello Nizar, are the removal of @since in this PR intentional? I haven't checked all of them, but this specific removal appears incorrect, since this method was indeed introduced in Java 22 as part of https://bugs.openjdk.org/browse/JDK-8318096.

Hello Jaikiran,
in jdk21 DHPPublicKey did have a getParams() method, so it is not new in jdk 22. It also existed before that

If you haven't looked at the other cases, I was about to group the changes related to the Key interfaces in a separate PR if that's fine. let me know what you think

Hello,

While the override of getParams in DHPublicKey was added, the getParams method has been inherited to DHPublicKey for a long time from DHKey. E.g., I can take this:

import javax.crypto.interfaces.DHPublicKey;

public class DhkeyTest {

    public static void main(DHPublicKey key) {
        System.err.println(key.getParams());
    }
    
}

and compile using JDK 8 without any compile-time errors. So, it would make more sense to me to not add the @since for it.

I believe Nizar will separate the changes to the Key interfaces into a separate PR, so we can discuss in more detail there.

Thanks!

Hello Jan, interesting. I hadn't noticed that javax.crypto.interfaces.DHPublicKey already was exposing getParams() in earlier versions because javax.crypto.interfaces.DHPublicKey extends from javax.crypto.interfaces.DHKey which has the getParams() method.

I believe Nizar will separate the changes to the Key interfaces into a separate PR, so we can discuss in more detail there.

That sounds fine to me.

The @since 14 was added here as part of https://bugs.openjdk.org/browse/JDK-8187898. The CSR explains what the changes were https://bugs.openjdk.org/browse/JDK-8230625. As noted in that CSR's specification (and attached images), the change for this method in that issue ended up being just API clarification (through a @apiNote) and no other change to this specific method. It continued to have the same signature including the throws clause that was previously available on this class through the super FilterOutputStream#write(byte[]) method.

So removing this @since 14 looks correct to me.

This method was introduced in Java 11 through https://bugs.openjdk.org/browse/JDK-6341887. It appears to be an oversight that a @since 11 wasn't added to this method in that change, because other new methods introduced in that change did come with a @since 11. So this addition of @since 11 now looks fine to me.
