Java安全异常BIRT和Apache POI Hack(Java Security Exception BIRT and Apache POI Hack)

 我得到了一个  
java.lang.SecurityException: class "org.apache.poi.POIXMLDocument"'s signer information does not match signer information of other classes in the same package
 
 在BIRT核心jar和Apache POI jar之间， 如BIRT错误报告所述。  
 错误报告中已经说明了这可以通过升级BIRT来修复，但是当我这样做时，我遇到了另一个运行时错误，只能通过降级来解决。 因此，就目前而言，我在这里有点腌渍。 这个评论说我应该能够解压缩apache poi jar，删除安全信息（BIRT清单中没有），然后重新压缩它，我应该好好去，但是当我删除安全信息时，我的代码是使用apache poi不再编译，就好像poi依赖不再存在（是的，它在类路径上）。 此外，我也从我的aspectj weaver抛出异常。

 如您所见，我删除了所有安全信息。 我一路走错了吗？ 这是我的问题的有效解决方案吗？ 

I'm getting a  
java.lang.SecurityException: class "org.apache.poi.POIXMLDocument"'s signer information does not match signer information of other classes in the same package
 
between the BIRT core jar and an Apache POI jar, as described by this BIRT bug report. 
It has been stated in the bug report that this can be fixed by upgrading BIRT, however when I do that I run into another runtime bug which can only be solved by downgrading. Thus, as it stands I am in a little bit of a pickle here. This comment says that I should be able to unzip the apache poi jar, delete the security information (there is none in the BIRT manifest), then rezip it and I should be good to go, however when I delete the security information my code that uses apache poi no longer compiles, its as if the poi dependency no longer exists (yes it is on the classpath). In addition i'm also getting an exception thrown from my aspectj weaver.

As you can see, I deleted all the security information. Did I do something wrong along the way? Is this a valid solution for my problem?

 修改迭代器来执行此遍历会很奇怪。 显而易见的事情就是根据需要编写“算法”：  
public static <T> void eachExceptLast(List<? extends T> list, Operation<T> op) {
     Iterator<T> iter = list.iterator();
     if (!iter.hasNext()) {
         return;
     }
     T item = iter.next();
     while (iter.hasNext()) {
         op.run(item);
         item = iter.next();
     }
}
 
 （或者使用假定RandomAccess列表的索引。）  
 但是，有一个更好的方法来做到这一点。 list.subList(0, list.size()-1) （对于非空列表）将返回原始列表的视图，而不是最后一个元素。 它不会复制，您甚至可以使用Iterator.remove 。 

It would be odd to modify the iterator to perform this traversal. The obvious thing to do is to write the "algorithm" as you want it: 
public static <T> void eachExceptLast(List<? extends T> list, Operation<T> op) {
     Iterator<T> iter = list.iterator();
     if (!iter.hasNext()) {
         return;
     }
     T item = iter.next();
     while (iter.hasNext()) {
         op.run(item);
         item = iter.next();
     }
}
 
(Or use an index assuming a RandomAccess list.) 
However, there's a much better way of doing this. list.subList(0, list.size()-1) (for a non-empty list) will return a view of the original list less the last element. It doesn't do a copy, and you can even use Iterator.remove.
