I was wondering about this too, or rather thinking that -XshowsSettings
might likely be used in conjunction with other options like -showversion
or VM specific options. For example, someone might do this:
java -XX+PrintCommandLineFlags -XshowSettings -showversion Foo
and the logs will capture the heap settings, the properties and locale
info printed by showSettings, and the HotSpot and JDK version printed by
-showversion. The only one that I'm sure is the default stack limit
(when -Xss<size> or -XX:ThreadStackSize=<size> isn't specified) as I
don't think we have a VM option to print that (except with
+PrintFlagsFinal dump of course).
