Eu tenho tentado instalar o openjdk 9 no Debian 9 e fazer com que tudo aponte para essa instalação. No entanto, algo está desativado e não deseja atualizar para o qual o comando java padrão no terminal aponta para.
Eu instalei o openjdk9 com um simples sudo apt-get install openjdk-9-jre openjdk-9-jdk
Se eu executar readlink $(which java) , ele aponta para /etc/alternatives/java
Se eu executar readklink /etc/alternatives/java , ele aponta para /usr/lib/jvm/java-9-openjdk-amd64/bin/java
Mas o mais estranho é que, se eu executar tudo de uma vez com readlink -f $(which java) , ele aponta para /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java
Qual é exatamente o que eu recebo quando eu corro java -version no terminal:
openjdk version "1.8.0_151"
OpenJDK Runtime Environment (build 1.8.0_151-8u151-b12-1-b12)
OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode)
O symlink default-java também aponta para o openjdk 8.
No entanto, javac -version no terminal parece certo:
javac 9.0.1
update-alternatives parece certo tanto para java quanto para javac :
$ sudo update-alternatives --config java
There are 2 choices for the alternative java (providing /usr/bin/java).

* 2 /usr/lib/jvm/java-9-openjdk-amd64/bin/java 1091 manual mode
$ sudo update-alternatives --config javac
There are 2 choices for the alternative javac (providing /usr/bin/javac).

* 2 /usr/lib/jvm/java-9-openjdk-amd64/bin/javac 1091 manual mode
Alguém tem alguma idéia de por que eu não consigo colocar o comando java de acordo com o resto do sistema? Ou tem ideias sobre o que mais pode tentar a seguir?
Muito obrigado.
