启动一个Java Standalone程序时报错

Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=256M; support was removed in 8.0

解决办法

从启动脚本中把-XX:MaxPermSize=256m参数删掉。

解释

根据官方文档Java命令行参数PermSize和MaxPermSize已经被移除和忽略。如果在命令行中使用，将会显示相应的警告。

The command line flags PermSize and MaxPermSize have been removed and are ignored. If used on the command line a warning will be emitted for each.
