-/**
- * INITIAL_USER_INFO is called by Android when it starts, and it's expecting a property change

- *
- * During normal circumstances, the emulator will reply right away, passing a response if
- * InitialUserInfoResponseAction::DEFAULT (so Android could use its own logic to decide which user
- * to boot).
- *
- * But during development / testing, the behavior can be changed using lshal dump, which must use
- * the areaId to indicate what should happen next.
- *
- * So, the behavior of set(INITIAL_USER_INFO) is:
- *
- * - if it has an areaId, store the property into mInitialUserResponseFromCmd (as it was called by
- *   lshal).
- * - else if mInitialUserResponseFromCmd is not set, return a response with the same request id and
- *   InitialUserInfoResponseAction::DEFAULT
- * - else the behavior is defined by the areaId on mInitialUserResponseFromCmd:
- * - if it's 1, reply with mInitialUserResponseFromCmd and the right request id
- * - if it's 2, reply with mInitialUserResponseFromCmd but a wrong request id (so Android can test
- *   this error scenario)
- * - if it's 3, then don't send a property change (so Android can emulate a timeout)

+ * But during development / testing, the behavior can be changed using lshal dump, which must use
+ * the areaId to indicate what should happen next.
+ *
+ * So, the behavior of set(INITIAL_USER_INFO) is:
+ *
+ * - if it has an areaId, store the property into mInitialUserResponseFromCmd (as it was called by
+ *   lshal).
+ * - else if mInitialUserResponseFromCmd is not set, return a response with the same request id and
+ *   InitialUserInfoResponseAction::DEFAULT
+ * - else the behavior is defined by the areaId on mInitialUserResponseFromCmd:
+ * - if it's 1, reply with mInitialUserResponseFromCmd and the right request id
+ * - if it's 2, reply with mInitialUserResponseFromCmd but a wrong request id (so Android can test
+ *   this error scenario)
+ * - if it's 3, then don't send a property change (so Android can emulate a timeout)
