@sunwei0325 老哥，拨号服务器这个怎么搭，有推荐教材么

迅雷极速版，刚试了下，无影响啊。。。。

借楼问下有没有大神知道如何突破公司的这种限制呢？

@qqpkat2 haha,3ks for u's tan cheng

@qqpkat2 不懂，还请赐教

@qqpkat2 这种怎么玩？记录的鼠标动作重放应该还有效吧？

@15015613 也就是说没个两周还是要手动一下了

@hubert3 虽然永久代是 Java8 移除的，但是在 Java 7 中，常量池就被移出了永久代，参见官方说明： [http://www.oracle.com/technetwork/java/javase/jdk7-relnotes-418459.html]( http://www.oracle.com/technetwork/java/javase/jdk7-relnotes-418459.html)
```
Area: HotSpot
Synopsis: In JDK 7, interned strings are no longer allocated in the permanent generation of the Java heap, but are instead allocated in the main part of the Java heap (known as the young and old generations), along with the other objects created by the application. This change will result in more data residing in the main Java heap, and less data in the permanent generation, and thus may require heap sizes to be adjusted. Most applications will see only relatively small differences in heap usage due to this change, but larger applications that load many classes or make heavy use of the String.intern() method will see more significant differences.

@adslxyz 请问大神是怎么在这么多类里找到`java`这个字符串是出现在哪个类呢

@yinheli
@adslxyz
感谢两位！

@lzx801 我其实在问之前反复看了这段话，然而我满脑子里反应的是字符串常量池是把它拷贝过去的。。。
不过看了 @yinheli 的回答才知道原来 JDK6 还真这么做的

@rozbo `java` 是被加载到 String 的字符串常量池了。但是 toString 不是返回一个新的 String 对象么？怎么会相等

惋惜

github 连接最好空一行，找了半天，当然，我可能眼睛坏了。。。

厉害了

@haozibi 活了，而且重新开源了，感觉不错，同在用
