Caused by: java.lang.OutOfMemoryError: PermGen space

permgen是內存中的一個位置，其中加載的類（顯然，在這種情況下，lambda表達式）被存儲。默認情況下它不會增長。您可以通過以下啓動選項Java（或把它放在JAVA_OPTS環境變量）：

-XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled 

允許它卸載類，並嘗試收集的PermGen空間。當然，如果你在一個時間需要大量的加載類，可以增加與

-XX:MaxPermSize=SIZE 

128M PermGen的空間是合理的價值，但我不知道如何類和拉姆達的方式 - 重申你的申請是。
