Is the application expected to set AutoRefresh to false if they plan to save the connection and restore it after an hour has passed?

I'm creating an application where I need to save the token to a file and restore it at a later time. after creating the getting the token:

String token = api.save();

I save the token to a file where I expect to be able to restore at later time (greater than 1h):

api2.restore(token);

During the first hour, everything seems fine. Afterwards, I get the following exception:

Exception in thread "main" com.box.sdk.BoxAPIException: The API returned an error code: 400
    at com.box.sdk.BoxAPIResponse.<init>(BoxAPIResponse.java:70)
    at com.box.sdk.BoxJSONResponse.<init>(BoxJSONResponse.java:30)
    at com.box.sdk.BoxAPIRequest.trySend(BoxAPIRequest.java:423)
    at com.box.sdk.BoxAPIRequest.send(BoxAPIRequest.java:209)

    at com.box.sdk.BoxAPIConnection.refresh(BoxAPIConnection.java:464)
    at test.App.main(App.java:38)

when I try, to use the connection to make a request:

BoxFolder folder = new BoxFolder(api, parentFolderId);
for (BoxItem.Info itemInfo : folder) {
    if (itemInfo instanceof BoxFolder.Info) {
        BoxFolder.Info folderInfo = (BoxFolder.Info) itemInfo;
        resultFolders.add(new BoxPluginFolder(folderInfo.getName(), folderInfo.getID()));
    }
}

I'm not sure what I'm expected to do. I'm not be able to refresh it aftwards.
