【问题描述】：
执行 java 桌面应用程序时，我得到一个 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也不会失败...
这可能是什么原因造成的？

【问题讨论】：
-
使用
-XX:MaxPermSize。 -
你能解释一下吗？它说“无法识别的 VM 选项 'MaxPermSize'”
-
你试过谷歌搜索吗？这是常识。
-
我只尝试过 -XX:MaxPermSize 这是我发现的第一件事，现在我正在尝试 -XX:MaxPermSize=1g
-
好吧，现在它不会抛出那个错误......但是另一个错误，但这与内存无关。谢谢。
