我正在运行 Ubuntu 14.04 并且需要使用 Java 7 update 71。似乎 openjdk 已在 Trusty repos 中更新为更新 71，但即使我安装了更新，java 似乎仍为版本 u65。

moorepants@moorepants-2170p:~$ sudo update-alternatives --config java
[sudo] password for moorepants:
There is only one alternative in link group java (providing /usr/bin/java): /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java
Nothing to configure.
我错过了什么？为什么 Java 版本不是 u71？
