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.
