> 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.
