See this wiki page:

You already have the suggested fix -- setting responseBuffering to 
adaptive.  You might try upgrading the driver.  If that doesn't work, 
you're probably going to need to talk to Microsoft about what you need 
to do differently on the JDBC url.

I did find this page:

This says that when using adaptive buffering, you should avoid using 
selectMethod=cursor.  So you should try removing that parameter.
