It is normal. Every conection has a name  in this case it is $Proxy4. I
saw similars names using OJB.

Are you ever tried to connect to the Database using JDBC from another tool
using the same driver? For example:

Squirrel SQL -

Sometimes the problem can be in the username - password. Also check if
