If jpackage is used to create a signed pkg file with an expired certificate specified with the "--mac-signing-key-user-name" option, it outputs an error message that the certificate is expired twice. It should write this error message only once.

E.g.:
---
jpackage --input MacSignTest/testExpiredCertificate.9987a58c/input --dest MacSignTest/testExpiredCertificate.9987a58c/output --name ExpiredCertificateMacSignTest --type pkg --main-jar hello.jar --main-class Hello --mac-sign --mac-signing-keychain jpackagerTest-expired.keychain --mac-signing-key-user-name "foo"
[12:20:08.025] Error: Certificate expired Developer ID Application: foo
[12:20:08.138] Error: Certificate expired Developer ID Application: foo
java.io.IOException: Command [/usr/bin/codesign, --timestamp, --options, runtime, -s, Developer ID Application: foo, --prefix, Hello., -vvvv, --keychain, jpackagerTest-expired.keychain, /var/folders/sp/mfz276114fq67h52dbd7vhb80000gn/T/jdk.jpackage11151639984216755252/images/image-2796044202651810900/ExpiredCertificateMacSignTest.app/Contents/runtime/Contents/Home/lib/libnet.dylib] exited with 1 code

When packaging a dmg or an app image with an expired certificate, the error is reported only once, as expected.
