please guys just take look at the class

@SuppressWarnings("serial")
@Entity
@Table(name = "delegation_rule")
@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
@DiscriminatorColumn(name = "main_type", discriminatorType = DiscriminatorType.STRING)
@DiscriminatorValue(value = DelegationRuleTypeString.SIMPLE)
public class DelegationRule implements IIdEntity 
 // --------------- variables -------------------- //

 @Id
 @Column(unique = true, nullable = false, name = "id")
 @GeneratedValue(strategy = GenerationType.IDENTITY)

 private long id;

 @Column(name = "main_type", insertable = false, updatable = false)
 private String mainType;

 @Column(name = "_index_")
 private int _index_;

 /** the type of the rule - defines the action **/
 @Enumerated(EnumType.STRING)
 @Column(name = "_type_")
 private DelegationRuleType _type_;

 @Column(name = "fall_through")
 private boolean fallThrough;

 // just in case we need some reserved values for later db changes
 @Column(name = "reserved_boolean")
 private boolean reservedBoolean;

 @Column(name = "reserved_integer")
 private int reservedInteger;

 @Column(name = "reserved_long")
 private long reservedLong;

 @Column(name = "reserved_string", columnDefinition = "TEXT")
 private String reservedString;

 @Column(name = "reserved_string_2", columnDefinition = "TEXT")
 private String reservedString2;
 // end reserved values

 /** a short description of this rule to help the users */
 @Column(name = "_description_", columnDefinition = "TEXT")
 private String _description_;

 /** the @link DelegationPath that this Rule belongs to */
 @ManyToOne(optional = true, fetch = FetchType.EAGER)
 @JoinColumn(name = "delegation_path_id")
 private DelegationPath delegationPath;

 // the delegate filter
 @ManyToOne

 // --------------- constructors -------------------- //

 public DelegationRule() 
 // mostly for hibernate
 

 public DelegationRule(DelegationRuleType type, String description) 
 this._type_ = type;
 this._description_ = description;
 

 // ---------------- getters and setters -------------------- //

 public String getMainType() 
 return mainType;
 

 public void setMainType(String mainType) 
 this.mainType = mainType;
 

 public long getId() 
 return id;
 

 public void setId(long id) 
 this.id = id;

 public DelegationPath getDelegationPath() 
 return delegationPath;
 

 public void setDelegationPath(DelegationPath delegationPath) 
 this.delegationPath = delegationPath;
 

 public int getIndex() 
 return _index_;
 

 public void setIndex(int index) 
 this._index_ = index;
 

 public AttributeDefinition getEmployeeAttributeDefinition() 
 return employeeAttributeDefinition;
 

 public void setEmployeeAttributeDefinition(AttributeDefinition employeeAttributeDefinition) 
 this.employeeAttributeDefinition = employeeAttributeDefinition;
 

 public DelegationConditionOperation getEmployeeOperation() 
 return employeeOperation;
 

 public void setEmployeeOperation(DelegationConditionOperation employeeOperation) 
 this.employeeOperation = employeeOperation;
 

 public String getEmployeeFilterValue() 
 return employeeFilterValue;
 

 public void setEmployeeFilterValue(String employeeFilterValue) 
 this.employeeFilterValue = employeeFilterValue;
 

 public boolean isFallThroughEnabled() 
 return fallThrough;
 

 public void setFallThrough(boolean fallThrough) 
 this.fallThrough = fallThrough;
 

 public void copyEmployeeFilter(DelegationRule original) 
 employeeAttributeDefinition = original.employeeAttributeDefinition;
 employeeOperation = original.employeeOperation;
 employeeFilterValue = original.employeeFilterValue;
 

i canot do anything more if the tables are not being created
i tried every things possible to change

Where is the Problem in this Mapping ?
i have hibernate 5.4.1 and Mysql 8
