Is there a password character set limitation in the Postgresql Connector?

I am trying to connect Tibco Spotfire Desktop using the Connector for Postgresql. 

When I try a postgresql account that has a '+' (plus sign) in the password it says:  
  "The data source does not exist or it does not respond."

The postgresql server log shows:
  'FATAL:  password authentication failed for user "test" '

When changing the password and removing special characters the Connector connects to the database without problem. 
Passwords with special characters works fine with other products connecting to the server.

There seems to be some sort of password string handling problem with the Tibco Postgresql Connector.
