java - 线程 "AWT-EventQueue-0"java.lang.OutOfMemoryError : PermGen space 中的 xception

Question

执行 java 桌面应用程序时，出现 java.lang.OutOfMemoryError: PermGen space。

我尝试增加 java 堆大小，将此参数传递给 VM:

-Xmx1g

但它总是失败。如果任何其他同事在他们的计算机上运行它，它不会失败...

这可能是什么原因造成的？

Answer 1

正如 Marko Topolnik 所说，

-XX:MaxPermSize 就是答案。

-XX:MaxPermSize=1g 成功了。
