我试图将一个对象添加到ArrayList并抛出ArrayIndexOutOfBoundsException以下是代码

private void populateInboxResultHolder(List inboxErrors){
    inboxList = new ArrayList();
    try{                
        inboxHolder = new InboxResultHolder();
        //Lots of Code
        inboxList.add(inboxHolder);
    }catch(Exception e){
        e.printStackTrace();
    }
}

例外是

但是根据ArrayList.add的签名,它不应该抛出这个异常.请帮忙.

this指针如何指向对象本身？它是java实现还是编译器实现？

在Spring源代码中找到了这段代码.这是将XML文件转换为Bean Tree的第一步.

/** Synchronization monitor for the "refresh" and "destroy" */
    private final Object startupShutdownMonitor = new Object();

public void refresh() throws BeansException, IllegalStateException {
        synchronized (this.startupShutdownMonitor) {
            // Prepare this context for refreshing.
            prepareRefresh();
}
