OK, thanks!
It occurs to me that I'm essentially trying to do the work that the
SecurityManager would have done in the past: Restrict access to
packages (or in this case, entire modules).

the new stream A when B
reaches EOF). It uses a constant amount of storage (the fixed-size read
buffer per-stream) and doesn't seem to consume any extra file
descriptors (because the JVM is obviously just reading bytes from a
ZipEntry that it already has open behind the scenes).

tty awful!
Are there any plans to implement anything that's capable of signing
macOS binaries and resources in a platform-independent way so that
jlink-produced distributions can work without warnings? Is that even a
reasonable thing to request? I've no idea how "private" Apple
he jar for something that looks like a
module-info.class, but I'd prefer not to have to. Is there a standard
method in the JDK that can find the module descriptor class file for me
based on the rules the JVM uses to find the descriptor upon loading a
jar?

Yes, I'm planning to move to this from ASM.

until after they'd appeared doesn't mean you should miss the events.
OSGi does handle this (it's written into the spec), but I don't know
quite how the implementations handle it.

How do the BSDs cope with this?
I suspect that OpenBSD will not have any support for this at all, but
FreeBSD might.

Inserting version information obviously breaks reproducibility, so it'd
be nice if it could be turned off!
The sources to the above module descriptor are available [2] if anyone
wants to try compiling this for themselves. The SHA256 of the resulting
module-info.class should be
e7a94b5a2788a3c5cd6d7f586e70a0f2138a2eaa0e75144b6a16e75c4b297870 if
your compiler produces the same output as mine.

That is another good point! This build is the one distributed on Arch
Linux. This was the procedure used to build it (no patches are applied):

a hack and wasn't future-proof. My tool is only
designed to work with JDK 9 and up.
Note that I'm *not* asking to get from loaded Class instances to
bytes: I'm analyzing classes statically and none of the analyzed
classes will actually be loaded by any ClassLoader.

Ah, thanks! I hadn't seen this. Looks like exactly what I need.
