Try to run the following command and make sure openjdk is the default JRE.

sudo update-alternatives --config java

Update

Try to run which java tell you which java is by default being used, and java -version see if env variables are correctly set.

I don't know what kind of game minecraft is, in browser (the plugin symbolic link may be broken) or client (try to launch it in a new Terminal session)?
