Bug Report: RapidMiner Server DB connection with no password
I've found a bug in RapidMiner Server 7.4. If you create a database connection using PostgreSQL on the server through the web interface which does not have a user password then it results in a NullPointerException when RapidMinerStudio tries to connect to it & update the JDBC connection information.
To resolve this issue you must put a space ' ' in the password box and then connection will be successful and RapidMiner Studio will not throw a connection error when communicating with the server.
Connections created in Studio do not show this behaviour, it is limited to Server only.
