[SOLVED] Authentication for CrateDB SU crate failed using CrateDB 5.10.3 with JDBC Driver

I'm trying to connect my CrateDB (running locally) with Java using JDBC.

public class Main {

    private static String connectionURL = "jdbc:postgresql://localhost:5432/";

    public static void main(String[] args) throws SQLException {

        Properties props = new Properties();
        props.setProperty("user", "crate");

        Connection sqlConnection = DriverManager.getConnection(connectionURL, props);

        if(!sqlConnection.isClosed()) {
            System.out.println("Connection is open!");
        } else {
            System.out.println("Connection is closed!");
        }
    }
}

Dependencies I'm using for this project:

    <dependencies>

        <dependency>
            <groupId>org.postgresql</groupId>
            <artifactId>postgresql</artifactId>
            <version>LATEST</version>
        </dependency>

        <dependency>
            <groupId>com.beust</groupId>
            <artifactId>jcommander</artifactId>
            <version>1.82</version>
        </dependency>

    </dependencies>

This is my current Main Class and its simple enough. The CrateDB SU does not have a Password (as said in the documentation) and shouldn't require one according to my auth settings in the crate.yml:d

auth:
  host_based:
    enabled: true
    config:
      0:
        user: crate
        address: _local_
        method: trust
      99:
        method: password

Yet when i try to run my Main Method i get the following error:

Exception in thread "main" org.postgresql.util.PSQLException: The server requested SCRAM-based authentication, but no password was provided.

If I add a Password Property, i also get the error that the SU password is empty and that authentification has failed. (And it is not possible to set a password for the CrateDB Superuser)

I tried adding a new User (Admin) and giving it a password as well as giving it all Priviliges but this fails also.

I have also tried using a different driver:

    <dependencies>

        <dependency>
            <groupId>io.crate</groupId>
            <artifactId>crate-jdbc</artifactId>
            <version>2.7.0</version>
        </dependency>

        <dependency>
            <groupId>com.beust</groupId>
            <artifactId>jcommander</artifactId>
            <version>1.82</version>
        </dependency>

    </dependencies>

But i get a error which is even weirder:

public class Main {

    private static String connectionURL = "jdbc:crate://localhost:5432/";

    public static void main(String[] args) throws SQLException {

        Properties props = new Properties();
        props.setProperty("user", "crate");

        Connection sqlConnection = DriverManager.getConnection(connectionURL, props);

        if(!sqlConnection.isClosed()) {
            System.out.println("Connection is open!");
        } else {
            System.out.println("Connection is closed!");
        }
    }
}

The Error i get:

    ... 4 more

So i would like to stick to the PostgreSQL driver instead of the crate.io Driver provided.

I have tried to google but i simply cannot find anything (or im blind) so any help would be appreciated.

I tried to get a JDBC Connection running with my Java-Project and expected a simple "Connection is open!" from my program so i know my Java-Code connects with Crates JDBC driver.
