Oracle 从resultset休眠不正确的分组

我正在尝试使用Hibernate检索一个实体及其子实体。它大部分时间都很好用。但是，有时子实体分组不正确，这是随机发生的。让我试着解释一下

我的实体类-

员工（母公司）：

EmployeeRolePK（EmployeeRole的主键）：

获取员工和员工角色的标准：

Criteria criteria = this.getSession().createCriteria(Employee.class);
criteria.add(Restrictions.in("id", parameterList));
List<Employee> entities = criteria.list()

这可能是什么原因？非常感谢您的帮助。谢谢
版本：Hibernate 4.2.8，commons dbcp 1.4

编辑：经过多次重试，我们已经将问题范围缩小到JDBC驱动程序或Oracle本身。我们通过JDBC运行hibernate生成的查询，遇到了相同的问题。我们还发现了一种模式来重新创建此错误传递随机输入参数，但第一次失败。如果使用相同的参数重试，则效果良好。我们也曾在SQLDeveloper中看到过这个错误。
以下是问题-

select emprole0_.EMP_ID as EMP_2_49_1_, emprole0_.EMP_ROLE_EFF_DT as EMP_ROLE1_25_1_, emprole0_.EMP_ID as EMP_2_25_1_, 
emprole0_.ROLE_ID as ROLE_ID3_25_1_, emprole0_.ROLE_TYP as ROLE_TYP4_25_1_, 
emprole0_.EMP_ROLE_EFF_DT as EMP_ROLE1_25_0_, emprole0_.EMP_ID as EMP_2_25_0_,
emprole0_.ROLE_ID as ROLE_ID3_25_0_, emprole0_.ROLE_TYP as ROLE_TYP4_25_0_, emprole0_.EMP_ROLE_EXPT_DT as EMP_ROLE5_25_0_ 
from EMP_ROLE emprole0_ where emprole0_.EMP_ID in (
select this_.EMP_ID from EMP this_ where this_.EMP_ID in (?, ?, ?)
)

如果删除了内部查询，则每次都可以正常运行。但是对于内部查询，结果有时是不正确的。我猜SQLDeveloper也使用JDBC驱动程序，所以这似乎是一个驱动程序问题。我们可能会尝试使用SQLPlus

版本-Oracle 12c、ojdbc7

您可以使用不同的角色ID准备数据吗？对于DB中的每一行，都将是不同的，我们可以在更新角色id和仅重复员工id后判断此日期是否重复，或者mappingI检查是否有问题。我已经更新了数据集。我已经用最新的发现更新了问题。。这似乎是JDBC驱动程序的问题。

@Embeddable

    @Column(name="EMP_ID")
    private String empId;

    //--Getters and Setters--

    public boolean equals(Object other) {
        // --NUll and InstanceOf checks--
        EmployeeRolePK castOther = (EmployeeRolePK)other;
        return this.empId.equals(castOther.empId) && (this.roleId == castOther.roleId) 
            && this.roleTyp.equals(castOther.roleTyp) && this.empRoleEffDate.equals(castOther.empRoleEffDate);
    }

    public int hashCode() {
        final int prime = 31;
        int hash = 17;
        hash = hash * prime + this.empId.hashCode();
        hash = hash * prime + ((int) (this.roleId ^ (this.roleId >>> 32)));
        hash = hash * prime + this.roleTyp.hashCode();
        hash = hash * prime + this.empRoleEffDate.hashCode();
        return hash;
    }
}

Criteria criteria = this.getSession().createCriteria(Employee.class);
criteria.add(Restrictions.in("id", parameterList));
List<Employee> entities = criteria.list()
