Error with parsing Hibernate Man.hbm.xml

Question

I can not run my hibernate application. I'm constantly getting this error:

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/C:/Users/MAG/.m2/repository/org/slf4j/slf4j-jdk14/1.7.2/slf4j-jdk14-1.7.2.jar!/org/slf4j/impl/StaticLoggerBinder.class]

The idea of my program is that: Man is super class for Owner and Renter.
Owner can have many Flats but Flat can have one Owner.
Renter can have many RenterBills but RenterBill can have one Renter.
Renter can have many Flats and Flats can have many renters.

My Man.hbm.xml:

<class name="Man" table="MEN">
    <id name="id" column="MAN_ID">
        <generator class="native" />
    </id>
    <property name="pesel" column="MAN_PESEL" />
    <property name="idNumber" column="MAN_ID_NUMBER" />
    <property name="email" column="MAN_EMAIL" />
    <property name="name" column="MAN_NAME" />
    <property name="surname" column="MAN_SURNAME" />
    <property name="telephoneNumber" column="MAN_TELEPHONE_NUMBER" />
    <many-to-one name="address" column="ADDRESS_ID" not-null="true" />

    <joined-subclass name="Owner" table="OWNERS">
        <key column="MAN_ID" />
        <property name="password" column="OWNER_PASSWORD" not-null="true" />
        <property name="seed" column="OWNER_SEED" not-null="true" />
        <set name="flats" table="OWNER_FLATS">
            <key column="MAN_ID" />
            <many-to-many name="flats" column="FLAT_ID" class="Flat" />
        </set>
    </joined-subclass>

    <joined-subclass name="Renter" table="RENTERS">
        <key column="MAN_ID" />
        <set name="flats" table="RENTER_FLATS">
            <key column="MAN_ID" />
            <many-to-many name="flats" column="FLAT_ID" class="Flat" />
        </set>
        <set name="bills" table="RENTER_BILLS">
            <key column="MAN_ID" />
            <many-to-one name="bills" column="RENTER_BILL_ID" class="RenterBill" />
        </set>
    </joined-subclass>
</class>

Java classes: Man.java

package model.man;

    private int id;

    private String idNumber;
    private String email;

       /* getters setters */
}

Owner.java

package model.man;

import model.flat.Flat;

public class Owner extends Man implements Iterable<Flat> {

    private String password;
    private String seed;
    private Set<Flat> flats;

    /* getters setters */
}

Renter.java

package model.man;

import java.util.HashSet;
import java.util.Set;

import model.bills.RenterBill;
import model.flat.Flat;

public class Renter extends Man {

    private Set<Flat> flats = new HashSet<Flat>();
    private Set<RenterBill> bills = new HashSet<RenterBill>();

Try removing the 'name' attribute from your many-to-many tag.

UPDATE

You have a set mapped as a many-to-one as well. This typically shows up in your Java POJO as a single instance of the referenced class. You may have meant to use a one-to-many tag there.
