引起：java.lang.OutOfMemoryError：PermGen space

permgen是内存中的一个位置，其中存储了加载的类（显然，在本例中为lambdas）。默认情况下它的大小不会增加。您可以将以下启动选项传递给Java（或将其放在JAVA_OPTS环境变量中）：

-XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled

允许它卸载类并尝试收集PermGen空间。当然，如果你需要一次加载的很多类，你可以用

增加PermGen空间

-XX:MaxPermSize=SIZE

128M是一个合理的值，虽然我无法知道你的应用程序是如何类和lambda重的。
