Why is /usr/lib/default-java pointing to the “wrong” jdk?

I got a linux mint pc with openJDK 1.11 pre-installed. I installed the openJDK 1.8. package and set the default java (sudo update-alternatives --config java) to it. All is working fine (java -version outputs the correct java version). Now that I try to use maven, in my attempt to change JAVA_HOME (because it was not pointing to the correct location - this is working now, too), I saw a directory called default-java (/usr/lib/jvm/default-java) which is a symlink to the original 1.11 JDK, even though I am not using it at all.



Can someone tell me what that means, if that is a problem and if I should change it?



Thanks in advance!

Like this: login screen Nothing to be log when I run flutter run --verbose, so I logged manually. Every tapping on field, the widget called dispose -> init -> build.
