java - 线程 "main"java.lang.NoClassDefFoundError : Xms256M 中出现异常

启动 WAS 8.5 服务器时，我在控制台中收到以下错误消息。一个多小时以来，进度状态正在开始...... 我相信存在一些配置问题，但无法找到它。我正在使用 java 7 和 Eclipse Kepler。

一个简单的缺失减号:

<vmarg name="-Dsun.java.command=-Xms256M -Xmx1024M -Djava.library.path=C:\WAS8/lib/native/win/x86_64/;C:\WAS8\java\jre\bin\compressedrefs;C:\..." />

注意-Xms256M中的减号...
