JAVA client iterator repopulates after exceeding maxKeys limit

[domantasVizinis]

When using JAVA minio client listObjects operation, the returned iterator repopulates after exceeding maxKeys limit.

Expected Behavior

Iterator hasNext method should not repopulate when maxKeys limit was set.

Current Behavior

S3Base class populates till it gets isTruncated as false from server

Steps to Reproduce (for bugs)

1. Populate minio bucket;
2. Make listObjects request with JAVA client and set maxKeys value.

Your Environment

• minio 8.4.6

listObject() is a recursive listing where maxKeys means how many keys (objects) need to be fetched in each ListObjects S3 API.
