🟡 Changes recommended
There are a few concrete correctness/quality issues in the updated code and UI (notably misleading 403 error messaging and minor cleanup) that should be addressed before approval.
Once you've addressed the issues Copilot identified, you can request another Copilot review.
Pull request overview
This PR addresses issue #244 by preventing the REST API plugin’s /system/properties endpoints from exposing or allowing modification of system properties that configure the REST API plugin itself (notably authentication-related settings). It does so by migrating plugin settings to Openfire’s typed SystemProperty API (scoped to plugin "REST API") and by filtering/forbidding access to all properties owned by that plugin.
Changes:
- Migrates REST API plugin configuration (enabled/auth type/secret/allowed IPs/custom auth filter/logging) from raw
JiveGlobalsaccess to typedSystemPropertydefinitions. - Adds enforcement in
SystemControllerto filter plugin-owned properties from listings and reject GET/PUT/POST/DELETE on those keys with HTTP 403. - Updates admin UI usage, OpenAPI annotations, i18n property descriptions, and adds Hurl e2e coverage for forbidden keys.

- Around line 322-326: Update the property filter in the system-property
endpoint to exclude every key beginning with the `plugin.restapi.` prefix, in
addition to the existing `pluginName` check. Preserve the current protection for
properties associated with `RESTServicePlugin.ENABLED`, and apply the prefix
guard even when MUC-related properties have not yet been registered.
In `@src/java/org/jivesoftware/openfire/plugin/rest/RESTServicePlugin.java`:
- Around line 76-91: Update the AUTH_TYPE migration or compatibility handling so
legacy plugin.restapi.httpAuth values outside basic, secret, and custom are
explicitly mapped to their intended authentication mode instead of relying on
SystemProperty.getValue() to default silently to AuthType.basic. Keep valid
AuthType values unchanged and anchor the change to AUTH_TYPE and its existing
property-loading path.

SystemControllerTest was passing locally and failing in CI due to test ordering. If a test set up the XMPPServer mock and didn't tear it down before this test, then this test would pass. Otherwise this would fail. This commit adds its own mock for SystemControllerTest and fixes the teardowns in other tests, ensuring a consistent state for the future.

I'm happy with this, but then I've also added changes since @guusdk last saw it, so I'll leave it for him to merge once he's checked what I've done :)
