Hi Peter,
This is awkward but I've seen method that is marked deprecated for removal
which simply throws an UnsupportedOperationException.
Suppose someone has an "enhanced" jarsigner that is also calling the JarSigner
API. It might also support customized ContentSigner but is also used by no one. If the
classes were removed the tool will not compile. If the classes remain but JarSigner no
longer uses it, it will simply throws an UOE which is harmless to most people.
Maybe the tool maintainer has already added "@SuppressWarnings("deprecated")", but this
time they will see a new warning on "[removal]", and they will know they need to remove it within a
year.

Hi Max,
What I was trying to say is that even if you remove ContentSigner
class(es) from JDK 15, users will still be able to compile either the
special "enhanced" jarsigner or the ContentSigner implementations if
they use -release 14 option. They will just not be able to run the
"enhanced" jarsigner with JDK 15. So removing a class from JDK 15 is not
so bad as it was before the -release option was available. At least from
the standpoint of compilation. So it makes a little difference if you
remove the classes or not when you also remove the options to use/run
the classes with jarsigner. What you choose is of course up to you. I
see Sean is suggesting that you keep the options in the jarsigner for
JDK 15.

Which brings me to this...
If it is a requirement to use -release option to compile ContentSigner
implementation class in order for them to be usable (with some older release of
jarsigner), then ContentSigner classes could as well be removed from the JDK 15
API because their signature will still be available to the javac with
appropriate -release 14 or older option. So compilation would still succeed.

What's the use of allowing compiling some classes if those classes can't be
used anywhere? They would be unusable in the new release of jarsigner. Ok, they
could be used in some older jarsigner if the classes were compiled with
appropriate -release option. So the usecase for not removing the classes would
be in a project that builds an implementation of ContentSigner and then
publishes it to be used in a project that still uses an old jarsigner. Such
ContentSigner project could then be upgraded to use the new JDK/javac with
appropriate -release option for compiling ContentSigner implementation classes.

All info for signing are passed into a ContentSigner through a
ContentSignerParameters object. In order to pass more info, I’ll need to create
new interface methods for it.
But you can just use your solution in JarSigner in the webrev below where you
are calling PKCS7.generateSignedData instead of ContentSigner. Just because the
ContentSigner APIs are still there doesn't mean you have to use it in jarsigner
(unless I am missing something).

Oh, I'll then need to add new fields to it to support RSASSA-PSS and EdDSA.
Sigh.
Why would you need to do that if they are deprecated?

We never actually deprecated the com.sun.jarsigner package with a
forRemoval=true flag, so while it may be very low-risk to remove these APIs, I
feel that we should not remove it w/o prior notice.
I would suggest adding the forRemoval=true for this package/APIs instead, and
plan on removing it in JDK 16 or 17.
I'm ok with removing the jarsigner options because the man page already warned
that they may be removed.
