Which appears to require a openjdk specific signing certificate, or sudo. Assuming you wanted to provide the cert, I would further assume you would still need to determine at runtime if you had the features available - meaning a openjdk runtime. Would checking this system property be the best, recommended, way to do that? java.runtime.name=OpenJDK Runtime Environment

I don't understand what you are asking. The signing certificate is only required at build time to sign the Mach-o binary of the JDK debugging tools. What do you need to know at runtime when you are using the tools?
