    Description

      When launching concurrently queries on multiple connections (1 query per connection) for the 1st time, some queries (which otherwise run without issue) fail with IndexOutOfBoundsException

      Here is a sample case where 2 threads (PipSQuawkling.java) executed 2 different queries on separate SQL Connection objects.

      2015-03-25 19:07:20 [pip1] INFO PipSQuawkling executeTest - [ 0 / 03_par100 ] Executing query...
      Query failed: IndexOutOfBoundsException: Index: 10, Size: 7

      2015-03-25 19:07:23 [pip1] ERROR PipSQuawkling executeQuery - [ 0 / 03_par100 ] exception while executing query: Failure while executing query.
      java.sql.SQLException: exception while executing query: Failure while executing query.
