cannot use oracle service name in datasource creation

When connecting to an Oracle data source, a SID is required for a connection and a service name can not be used.

The Oracle URL formats are:

With a SID you use ":sid" at the end

jdbc:oracle:thin:@//oraclehost:1521:mysid

with a service name you use "/myservicename"

jdbc:oracle:thin:@//oraclehost:1521/myservicename

The dialog box prevent removing the ":" and replacing it with the needed "/"
(not even via the driver definition where you seem to be allowed to set the url format...)
