Streaming result set null is still active

[Dyutiman Chaudhuri]

Hi,
I am using an ETL tool to fill up my DB. Its using JDBC. but i am getting the following error:
"Streaming result set null is still active. No statements may be issued when any streaming result sets are open and in use on a given connection. Ensure that you have called .close() on any active streaming result sets before attempting more queries."

I am using Innodb for all my of my tables.

Is there any solution for this?

thanks
