Not support Extension class

[mercuriy94]

Hello!
I'm trying to make an extension class, in the end I get an error:
`Error:Execution failed for task ':app:objectbox'.

Value for value should be of type String (could not convert from class org.greenrobot.eclipse.jdt.core.dom.SimpleName). Note: only inline constants are supported.`

My code:
`
@entity
@NameInDb(value = BOX_NAME)
public class User {

public static final String BOX_NAME = "users";

public static final String FIELD_ID = "id";
public static final String FIELD_UUID = "uuid";
public static final String FIELD_NAME = "name";
public static final String FIELD_SURNAME = "surname";

@Id
@NameInDb(FIELD_ID)
protected long mId;
@NameInDb(FIELD_UUID)
protected String mUuid;
@NameInDb(FIELD_NAME)
protected String mName;
@NameInDb(FIELD_SURNAME)
protected  String mSurname;
public User() {
}

@Generated(385108689)
@Internal
/** This constructor was generated by ObjectBox and may change any time. */
public User(long mId, String mUuid, String mName, String mSurnamer) {
    this.mId = mId;
    this.mUuid = mUuid;
    this.mName = mName;
    this.mSurname = mSurname;
}

public static User newInstance(UserDto userDto) {
    User user = new User();
    user.mName = userDto.getName();
    user.mSurname = userDto.getSurname();
    return user;
}

public long getId() {
    return mId;
}

public void setId(long id) {
    mId = id;
}

public String getUuid() {
    return mUuid;
}

public void setUuid(String uuid) {
    mUuid = uuid;
}

public String getName() {
    return mName;
}

public void setName(String name) {
    mName = name;
}

public String getSurname() {
    return mSurname;
}

public void setSurname(String surname) {
    mSurname = surname;
}

}

@entity
@NameInDb(value = BOX_NAME_EXTENSIOON)
public class ExtensionUser extends User{

public static final String BOX_NAME_EXTENSIOON =  "ext";
public static final String FIELD_TEST =  "test";

@Id
@NameInDb(FIELD_ID)
protected long mId;

@NameInDb(value = FIELD_TEST)
protected String mTestField;

}

`
I'm using version 9.9.12.
Thank you for your great work.
