一个离奇的 ArrayIndexOutOfBoundsException 异常的排查过程

今天同事遇到了一个离奇的ArrayIndexOutOfBoundsException,找我协助定位,定位的过程很有意思,故而记录一下。

先按时序复盘一下

  • 项目原先可正常运行。

  • 没有修改任何依赖的情况下,从另一个项目移植了 工具 BeanValidationUtil 后,报如下异常:

    org.springframework.web.context.ContextLoader.initWebApplicationContext(ContextLoader.java:307) | Context initialization failed
    org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read candidate component class: file [/Users/xxxxxxxxx/BeanValidationUtil.class]; nested exception is java.lang.ArrayIndexOutOfBoundsException: 48959

造成异常的工具类

/**
 * JSR349 Bean Validation工具类
 *
 * @author limu.zl
 */
public class BeanValidationUtil {
    /**
     * 验证失败时抛出ConstraintViolationException
     *
     * @param object 待验证对象
     * @param groups 验证group
     */
    public static void validateWithException(Object object, Class<?>... groups) {
        ValidatorFactory validatorFactory = Validation.buildDefaultValidatorFactory();

        // 国际化,强制用中文,ref:https://docs.oracle.com/javase/tutorial/i18n/locale/create.html
        Locale locale = new Locale.Builder().setLanguage("zh").setRegion("CN").build();

        // 国际化,指定语言,ref:https://www.ibm.com/developerworks/cn/java/j-cn-hibernate-validator/index.html
        MessageInterpolator interpolator = new LocalizedMessageInterpolator(validatorFactory.getMessageInterpolator(), locale);

        Validator classValidator = validatorFactory.usingContext()
                .messageInterpolator(interpolator)
                .getValidator();

        Set<ConstraintViolation<Object>> constraintViolations = classValidator.validate(object, groups);
        if (!constraintViolations.isEmpty()) {
            String messages = constraintViolations.stream()
                    .filter(t -> t instanceof ConstraintViolationImpl)
                    .map(t -> {
                        ConstraintViolationImpl t1 = (ConstraintViolationImpl) t;
                        return String.format("出问题的字段:%s,问题:%s", t1.getPropertyPath(), t1.getMessage());
                    })
                    .collect(Collectors.toList())
                    .toString();
            throw new IllegalArgumentException(messages);
        }
    }
}

分析

如代码所示, BeanValidationUtil 是个工具类,根本不在Spring容器上下文里,但异常栈却报到Spring的包里去了。

  • 由于项目没有修改依赖,所以包冲突问题不太可能出现(这个项目原先也使用JSR349做Bean Validation),而且冲突的话异常应该是NoClassDefFoundError之类的异常。

  • 尝试降低Hibernate Validation的版本到4.x,故障依旧。

  • 百度、谷歌类似异常,无果。

经过20分钟的源码定位也没找到问题所在,于是我尝试逐步删除BeanValidationUtil的代码。发现当把lambda语法删光之后,项目就能正常启动了。

突然灵光一现,问同事 : “这TM是不是个非常古老的项目啊?”

同事:“对啊,四五年了吧……”

于是分析了下pom.xml,发现用的是 Spring 3 。隐约记得Spring 3不完全兼容JDK8,这个类中使用了 Java 8的语法,所以导致了问题。

结果确认

既然猜测是Spring 3和Java 8不兼容导致,故而在搜索时,将关键词改为: spring 3 java 8 ArrayIndexOutOfBoundsException ,果然印证了自己的想法。

  • ArrayOutOfBoundsException on Bean creation while using Java 8 constructs

  • Spring BeanDefinitionStoreExcept-nested exception is java.lang.ArrayIndexOutOfBoundsException: 53804

反思

犯了经验主义错误,基于Spring 3的项目已经三四年没有见过了(Dubbo不算,哈哈哈。因为Dubbo当初的版本虽然依赖了Spring 3,但其实实际项目一般都会exclude掉,换上Spring 4),一直以为是个Spring 4的项目,没有从Spring版本与JDK的兼容性的方向上去考虑。

浪费了半小时。
