您好，我在 kubuntu 11.10 上安装 Java 后收到警告。Java 程序运行，但我总是收到 4 个警告：
$ java
Warning: no leading - on line 1 of `/usr/lib/jvm/java-6-sun-1.6.0.26/jre/lib/amd64/jvm.cfg'
Warning: missing VM type on line 1 of `/usr/lib/jvm/java-6-sun-1.6.0.26/jre/lib/amd64/jvm.cfg'

Warning: missing VM type on line 1 of `/usr/lib/jvm/java-6-sun-1.6.0.26/jre/lib/amd64/jvm.cfg'
我错过了什么？提前致谢！文件 /usr/lib/jvm/java-6-sun-1.6.0.26/jre/lib/amd64/jvm.cfg 的内容是：
/usr/lib/jvm/java-6-sun

似乎当前的 jvm.cfg 无效，并且/usr/lib/jvm/java-6-sun不应该出现在第一行。
注释掉此行（在前面添加#）并尝试查看是否仍然出现错误/警告。
