最近项目在生产环境抛错：
at org.hibernate.impl.SessionFactoryImpl.get(SessionFactoryImpl.java:339) at org.hibernate.impl.SessionFactoryImpl.getQuery(SessionFactoryImpl.java:411) at org.hibernate.impl.SessionImpl.getQueries(SessionImpl.java:884) at org.hibernate.impl.SessionImpl.iterate(SessionImpl.java:920) at org.hibernate.impl.QueryImpl.iterate(QueryImpl.java:41)
上述是调用Hibernate查询数据query.iterate();后，就抛错了，根据日志分析，错误日志记录的一般是java.lang.ArrayIndexOutOfBoundsException: -68，后面是一个-128范围内的负数，并且根据时间逐渐增大，比如到java.lang.ArrayIndexOutOfBoundsException: -2，然后java.lang.ArrayIndexOutOfBoundsException: -1，然后又轮回到java.lang.ArrayIndexOutOfBoundsException: -127。
开始看了半天一直在找自己代码的问题，最后通过查看hibernate源码SessionFactoryImpl.java的339附近代码，方法如下：
private synchronized Object get(Object key)
Object result = this.softQueryCache.get(key);
if (result != null) {
this.strongRefs[(++this.strongRefIndex % 128)] =
this.strongRefs[(++this.strongRefIndex % 128)] =为第339行，strongRefs数组是初始化长度为128的数组，strongRefIndex被定义为：private transient int strongRefIndex = 0;
strongRefIndex是根据每次获取数据都递增1的，根据报错内容，应该是strongRefIndex为负数了，而且每次也确实在递增。
通过上述分析，strongRefIndex字段要不内存中被无故修改了，或者就是递增到int的最大长度了，导致变为了负数。好像没有其他办法，只能重启网站，重启后问题果然解决了！
