CodeCahe是完整的java7

Question

当我们编译java分类

时，我遇到了错误

使用java版本 java版＆＃34; 1.7.0_11＆＃34; Java（TM）SE运行时环境（版本1.7.0_11-b21） Java HotSpot（TM）64位服务器VM（版本23.6-b04，混合模式）

我试图将reservedcodeCachesize增加到80M也无法正常工作。对此有任何建议会非常有用吗？

除了将其增加到384m之外，您还可以尝试启用代码缓存刷新它，应该可以工作。

-XX:ReservedCodeCacheSize=384m
-XX:+UseCodeCacheFlushing
