Code Signing

[C4J]

I include your library in my project and I'm just starting to create installers for my app using install4j and of course Apple now seem to require that programs downloaded from the internet have appropriate code signing.

When I attempt to create an installer packaged and upload to Apple for Notarize I get this error back.

So I am wondering - can these binaries be signed ?

jSerialComm-2.11.0.jar/OSX/x86/libjSerialComm.jnilib

"message": "The binary is not signed.",
"message": "The signature does not include a secure timestamp.",
"message": "The binary is not signed with a valid Developer ID certificate.",
