冲突的枚举值 java

Question

我在 2 个单独的文件中定义了 2 个枚举，如下所示： MyErrorCodes.java

@Getter
public enum MyErrorCodes implements ErrorCode {
    ERROR1(90, 1, 01),
    ERROR2(90, 1, 02),
    ERROR3(90, 1, 03),
    ERROR4(90, 1, 04),
    ERROR5(90, 1, 05);
    ....
}

ErrorCategory.java

public class ErrorCategory {
@AllArgsConstructor
    public enum ErrorCodes {
        EXECUTION_ERROR("execution.error", "Error in executing {0}.", INTERNAL_ERROR,
                             MyErrorCodes.ERROR1),
        DESERIALIZATION_ERROR("...", "...",BAD_REQUEST_ERROR, MyErrorCodes.ERROR2),
        DEFAULT_INTERNAL_ERROR("...", "...", INTERNAL_ERROR, MyErrorCodes.ERROR3),
        INVALID_RESPONSE("...", "...", INTERNAL_ERROR, MyErrorCodes.ERROR4),
        MAPPING_ERROR("...", "...", INTERNAL_ERROR, MyErrorCodes.ERROR5);
   }
}

在运行时出现错误：

Conflicting enum values. Name 'ERROR4' uses ordinal value (4) that is also used for name 'MAPPING_ERROR'

ERROR4 是枚举#1 中的第 4 个元素，而 MAPPING_ERROR 是枚举#2 中的第 5 个元素。那为什么当它们是完全不同的枚举时我会收到冲突错误？

P.S。 enum#1 实现的接口如下所示：

public interface ErrorCode {
    int getErrorCode();
    String getKey();

}

好的，下面是我们针对该问题所做的工作和发现：

我们使用 ignite cluster 进行部署，我们将 ignite 版本从 6 更新到 7 并解决了问题。

Ignite 缓存枚举值，所以当我们引入新的枚举值时，我们应该添加到末尾以增加序号以避免将来发生冲突或清除缓存。
