warning: ignoring option PermSize=256m; support was removed in 8.0

使用jdk1.8后，控制台出现下面提示信息：

Java HotSpot(TM) 64-Bit Server VM warning: ignoring option PermSize=256m; support was removed in 8.0
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=768m; support was removed in 8.0

在windows-》preferences中：

 在edit中，将下面jvm中PermSize和MaxPermSize去掉即可。
