线程“AWT-EventQueue-0”java.lang.OutOfMemoryError中存在异常：PermGen空间

当执行java桌面应用程序时，我得到一个java.lang.OutOfMemoryError:PermGen空间

我已尝试增加java堆大小，并将此参数传递给VM：

-Xmx1g

但它一直在失败。如果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

正如Marko Topolnik所说

-答案是MaxPermSize

---

-XX:MaxPermSize=1g成功了。

使用-XX:MaxPermSize。你能解释一下怎么做吗？上面写着无法识别的虚拟机选项“MaxPermSize”，你用谷歌搜索过吗？这是常识。我已经尝试了-XX:MaxPermSize，这是我发现的第一件事，现在我正在尝试-XX:MaxPermSize=1gWell，现在它不会抛出那个错误。。。但另一个，但这与记忆无关。塔克斯。
