Java Yourkit Profiler显示5K + char []对象没有被垃圾收集，如何辨别罪魁祸首？
[英]Java Yourkit Profiler showing 5K+ char[] objects not getting garbage Collected, how can I tell what class is the culprit?
问题描述
I have an RCP application and there is a slow memory leak and I recently started using YourKit Profiler which seems to be the best app out there for this. 
我有一个RCP应用程序，内存泄漏很慢，我最近开始使用YourKit Profiler，它似乎是最好的应用程序。 The question I have, is I see that over 20% of my objects char[] arrays and what I want to figure out is what class/method in my app is created all these instances as they do not seem to getting garbage collected. 我的问题是，我看到超过20％的对象char []数组，我想弄清楚的是，在所有这些实例中，我的应用程序都创建了什么类/方法，因为这些实例似乎没有被垃圾收集。 I am connected to a messaging server and consuming probably 500 text messages a second, but I am having a tough time using Yourkit to find the gradual memory leak. 我已连接到消息传递服务器，并且每秒可能消耗500条文本消息，但是使用Yourkit来查找逐渐的内存泄漏却很困难。 Thanks for any help. 谢谢你的帮助。

As a YourKit developer, I can recommend to record object allocations as it's described here http://www.yourkit.com/docs/11/help/allocations.jsp 作为YourKit开发人员，我可以建议记录对象分配，如此处http://www.yourkit.com/docs/11/help/allocations.jsp所述。
After that you'll see the places where each particular object was created. 之后，您将看到创建每个特定对象的位置。 Please note, that allocation recording adds (sometime significant) profiling overhead. 请注意，分配记录增加了（有时是很大的）性能分析开销。
