Hello Matthew, In recent times we have been adding more of these configuration debugging into the -XshowSettings option. I'm unusure to what extent this option should be advertized or used for gathering such details of the runtime. Would this be more suitable to be done as a `jcmd` command? Something like a `jcmd <pid> VM.security_configuration`? To me, that feels like a more natural place to be adding support for details like these. More so because I think it's very rare for applications to be launching the JVM with the `-XshowSettings` option.
