JDBC calls to interrupted threads throw sqlexceptions - when queries are moved into the medium queue

This happens in both 1.7.07, 1.7.08, and 1.7.08 with the patches currently available on github.

Create a query that times out and moves into the medium queue. The following error occurs:

[INFO] Located DataSource for hiveId=[i2b2demo] projectId=[/Demo/]
[INFO] Using datasource java:/QueryToolDemoDS
[ERROR] Error while executing sql

The initial (few) queries will finish once it is in the queue after this exception is raised.

This is a very similar bug to CORE-149.
