java.lang.OutOfMemoryError: PermGen space still exist

java.lang.OutOfMemoryError: PermGen space still exist

我在eclipse中通过tomcat调试一个项目，抛出如下错误： 而且日食不是没有反应，错误报告如

Daemon System Thread [Java2D Disposer] (Suspended (exception OutOfMemoryError)) owns: Win32GraphicsEnvironment (id=116) owns: FontStrikeDisposer (id=117) D3DGraphicsDevice.getDeviceCaps(int) line: 108 D3DGraphicsDevice.createDevice(int) line: 87

再次调试时，报错如

Exception in thread "Java2D Disposer"

我已经更改eclipse.ini和tomcat以扩大内存，但错误仍然存​​在

如何解决问题？提前谢谢你！

您需要通过 java 命令参数增加 PermGen 大小：

-XX:MaxPermSize=128M
