Java SDK how to get items if folder contains more that 300 000 items

Hello, I have a folder with 320000+ items inside. And when I try to get items info I got error: 

{"type":"error","status":400,"code":"bad_request","context_info":{"errors":[{"reason":"invalid_parameter","name":"offset","message":"Invalid value '301000'. The offset must not exceed the maximum offset of 300000"}]},"help_url":"http:\/\/developers.box.com\/docs\/#errors","message":"Bad Request","request_id":"*********"}

I'm use java SDK and admin account with "AsUser" header.
