JPackage and ask for microphone permissions broken on OSX...

[Andy Herrick]

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:
