> This patch adds a new jcmd diagnostic command, `VM.show_settings`, to make > the existing -`XshowSettings` output available from a running VM. The command > accepts the same sections as`XshowSettings` (all, vm, properties, locale, > security, system, security:all, security:properties, security:providers, > security:tls). > > HotSpot registers the new diagnostic command, validates the requested > section, then calls into `sun.launcher.LauncherHelper` to reuse the existing > show settings formatting and return the result as bytes for the jcmd stream. > The VM settings path also passes hotspots `InitialHeapSize`, `MaxHeapSize`, > and Java thread stack size into the Java helper. A new jcmd test covers VM, > properties, security TLS, and invalid-input output. > > --------- > - [x] I confirm that I make this contribution in accordance with the [OpenJDK > Interim AI Policy](https://openjdk.org/legal/ai).
