Fixed version (ground truth):
@Override public int enableSystemAppWithIntent(ComponentName who,Intent intent){
synchronized (this) {
    if (who == null) {
      throw new NullPointerException("String_Node_Str");
    }
    getActiveAdminForCallerLocked(who,DeviceAdminInfo.USES_POLICY_PROFILE_OWNER);
    int userId=UserHandle.getCallingUserId();
    long id=Binder.clearCallingIdentity();
    try {
      UserManager um=UserManager.get(mContext);
      UserInfo primaryUser=um.getProfileParent(userId);
      if (primaryUser == null) {
        primaryUser=um.getUserInfo(userId);
      }
      IPackageManager pm=AppGlobals.getPackageManager();
      List<ResolveInfo> activitiesToEnable=pm.queryIntentActivities(intent,intent.resolveTypeIfNeeded(mContext.getContentResolver()),0,primaryUser.id);
      if (DBG)       Slog.d(LOG_TAG,"String_Node_Str" + activitiesToEnable);
      int numberOfAppsInstalled=0;
      if (activitiesToEnable != null) {
        for (        ResolveInfo info : activitiesToEnable) {
          if (info.activityInfo != null) {
            if (!isSystemApp(pm,info.activityInfo.packageName,primaryUser.id)) {
              throw new IllegalArgumentException("String_Node_Str");
            }
            numberOfAppsInstalled++;
