BUG #1449: JDBC client driver bug waiting to happen

The following bug has been logged online:

Bug reference: 1449
Logged by: Michael Robinton
Email address: michael@insulin-pumpers.org

Operating system: linux
Description: JDBC client driver bug waiting to happen
Details:

if "int size" is set to 8, there is insufficient storage in "int n" to
accomodate 8 bytes of storage since jave thinks an int is 4 bytes. Since
currently no 8 byte longs are sent, this bug is not apparent.
