Summary
Fix in the IamAuthConnectionPlugin to prioritize the override property IAM_DEFAULT_PORT then Hosts port, and then Dialect port.
Description
Fix in the IamAuthConnectionPlugin to prioritize the override property IAM_DEFAULT_PORT then Hosts port, and then Dialect port.
This also results in change of behaviour. When an invalid port value is specified for IAM_DEFAULT_PORT, it no longer throws an exception, but rather logs a warning and then falls back on either the Host port or Dialect default port.
