我不知道为什么会这样。我在Windows计算机上编译程序的事实可能是问题吗？这是我唯一能想到的。

I do not know why this is happening. Could the fact that I compiled the program on a Windows computer be the problem? That is the only thing that I could think of.

推荐答案

在OS X下，Java的默认版本是Java 1.5。

Under OS X the default version of Java is Java 1.5.

确保正确的jvm的唯一好方法是使用java Web start。

The only good Way to ensure the right jvm is with java Web start.
