OK - I have reproduced this problem, filed an issue, and found the fix.
You can see the issue in https://bugs.openjdk.java.net/browse/JDK-8272639.
Basically another key is needed in application plist to cause
application to ask for microphone access.
It is far to late to get any fix into JDK17, but I will fix in JDK18 and
you can work around this issue in JDK17 (or JDK16) by using the
--resource-dir option:
/Andy
1.) create an empty directory test-resources
2.) copy from the openjdk sources the file
src/jdk.jpackage/macosx/classes/jdk/jpackage/internal/resources/Info-lite.plist.template
to test-resources/Info.plist.
3.) edit test-resources/info.plist to include the key:
<key>NSMicrophoneUsageDescription</key>
<string>The application is requesting access to the
microphone.</string>
4.) now add "--resource-dir test-resources" option to your jpackage
command, and it will use this plist template instead of the default one.

Hi Core-libs-dev,
I’m trying to report an issue with JPackage on recent versions of OSX.
Problem is, the microphone permissions aren’t granted to applications created
by jpackage. The resulting recorded 16 bit PCM line in samples files are the
correct duration, but don’t have any sound (samples all set to 0).
System Preferences -> Security & Privacy -> Privacy -> Microphone
(application never asks for permissions)
Otherwise, the only workaround I can figure out is to have the app launch then
bootstrap itself using Runtime and grant applications to the Terminal.app (when
it calls itself from `java Application.app/MacOS/Resources/Application`)
There are various reports of this on the Internet - but I’m wondering if the
JPackage team is aware of the issue.

This pretty much shows the solution - needs a bit of Objective C though.
Reproducing the problem: JPackage any java sound recording app on latest OSX,
run it... will be unable to capture sound. Run the same code from the command
line, via classpath or modules... it will record audio after asking the user to
grant microphone permissions to Terminal.app.
It would be great if this is fixed in JDK 17.
Many Thanks,
Ben S
