java.lang.IllegalArgumentException:没有枚举const类

Question

我使用JAXB 2来解析XSD架构的XML文件,并在ants构建到Java类期间自动解组XML标签.有些enums是创造的.代码是:

@XmlType(name = "binQuality")
@XmlEnum
public enum BinQuality {

    GOOD,
    BAD,
    UGLY,
    NULL;

    public String value() {
        return name();
    }

    public static BinQuality fromValue(String v) {
        return valueOf(v);
    }
}

在我的代码中我打电话:

BinQuality bq = BinQuality.valueOf(him.getToBinQuality());

在一个循环中,我只在第91次迭代中获得异常.

*******更新*******

him.getToBinQuality()确实返回有效的枚举(GOOD/BAD/UGLY/NULL).以下是日志的摘录.

这看起来真的很神秘.

使用的Java版本是1.5.

欣赏它.

这是因为您的第91个条目没有找到枚举值.失败的String的值是多少？
