从 java 1.5 移至 java 1.6.0_25 后，JVM 在负载下崩溃
我有一个在 JBoss 4.2.2.GA 上运行的企业应用程序，我在负载下遇到 JVM 崩溃。当我们迁移到 java 1.6.0_25 时，我们看到了这种行为，同一应用程序在 JDK 1.5 上运行良好，
我们观察到加载中的 java.lang.OutOfMemoryError: PermGen 空间，以下是 JVM 崩溃报告。
崩溃报告在这里，我删除了一些引用我的应用程序的行

I have an enterprise application running on JBoss 4.2.2.GA, I am experiencing JVM crash under load. We see this behaviour when we moved to java 1.6.0_25, the same application worked fine with JDK 1.5
we observer java.lang.OutOfMemoryError: PermGen space in load the following is the JVM crash report.
crash report is here, I removed some of the lines that references to my application

PermGen 空间是 JVM 存储用户定义对象的类定义的地方。 JDK 1.5 和 1.6 之间的 permgen 分配可能有所不同，并且几乎可以肯定这两个 JDK 生成的字节码有所不同，因此迁移后遇到问题也就不足为奇了。
使用以下开关在启动时为 JVM 分配额外的 permgen 空间：
-XX:MaxPermSize=XXXm其中 XXXm 是以兆字节为单位的数字。请注意不要使此数量太大，否则您可能会遇到其他与内存相关的问题。您可能还想利用 jvisualvm 来分析应用程序服务器的启动情况。也许你可以关闭一些不必要的功能。
PermGen space is where class definitions for user defined objects are stored by the JVM. It is likely that the permgen allocation differs between JDK 1.5 and 1.6, and it is almost certain that the bytecode generated by the two JDKs differs, so it's not surprising that you're running into issues after migrating.
Allocate additional permgen space to the JVM on startup with the following switch:
-XX:MaxPermSize=XXXmwhere XXXm is a figure in megabytes. Beware of making this amount too large or you will likely run into other memory-related issues.You might also want to make use of jvisualvm to profile your application server startup. Maybe you can turn off some unnecessary functionality.
（只是一个想法） - XML 处理随着时间的推移而发生了变化。流行的是使用字符串内部化 String.intern()，将 XML 标签放入永久内存中。这并不像看起来那么无辜。如今，通常使用唯一的映射来代替。也许您有旧的显式设置。 http://www.ibm.com/developerworks/xml/library /x-perfap1/index.html
(Just an idea) - XML handling has changed over time. Popular was using string internalizing String.intern(), throwing XML tags into Permanent Memory. That is not as innocent as it seems. Today often a unique mapping is used instead. Maybe you have old explicit settings. http://www.ibm.com/developerworks/xml/library/x-perfap1/index.html
