Java Debian 9 openjdk-7-jre和openjdk-7-jre-headless

需要使用需要openjdk7的程序。运行Debian 9 Mate

当我尝试安装时获得以下信息

$sudo apt-get install openjdk-7-jre openjdk-7-jre-headless

软件包openjdk-7*不适用于Debian stretch through

apt

，它仅适用于Debian

正确的软件包版本是，要在debian 9上安装，请运行：

sudo apt update 
sudo apt install openjdk-8-jdk openjdk-8-jre-headless

尝试改用openjdk-8-jre。认真地大多数用Java编写的程序将使用最新版本的Java运行。“上游”源不再支持Java 7。根据openjdk8-aarch64端口的自述文件，openjdk7是编译openjdk8所需的引导jdk。我找不到任何其他来源来证实这一点。安装jre 8不是运行在jre上的应用程序的解决方案7@HassanALAMI安全的方法是在debian Jessie上安装这两个包。从Debian Sid安装

openjdk-7-jdk

和

openjdk-7-jre-headless

将破坏您的系统，并且由于libfontconfig1（>=2.12）的不可满足依赖性，无法从实验存储库进行安装。那么，如果您有一个程序在运行时声明jvm 7，该怎么办？
