      Description

      I have a daemon that keeps a SQL connection open. It periodically checks the status of the connection using java.sql.Connection.isValid.

      I've been running this for months. Today I saw the method throw exception java.lang.IndexOutOfBoundsException. I dealt with it like I would an SQLException, but it suggests that there is a bug in the JDBC driver.

      Here's the method:

          public boolean connectionIsValid()
          {
              final int maxSecondsToWait = 2;
              
              boolean isValid;
              
              if (_conn == null)
              {
                  isValid = false;
              }
              else
              {
                  try
                  {
                      isValid = _conn.isValid(maxSecondsToWait);
                  }
                  catch (Throwable ex)
                  {
                      isValid = false;
                      _logger.error(String.format("AuditorDB.connectionIsValid error: %s", ex.toString()));
                  }
              }
              
              return isValid;
          }
