Starting Neo4j Enterprise 4.0 after update from repo on Fedora30 64bit fails because of Java version

Good evening,
On Fedora 30 64bit i did a dnf update, during this update from the repo Neo4j enterprise is updated to 4.0.
I removed the Plugins (algo and apoc 3.5) and did #sudo systemctl restart neo4j.
But neo4j won't start #journalctl says Neo4j cant be started using java version 1.8.0...
#use Oracle Java 11, OpenJDK 11.
So i did #sudo dnf install java-11-openjdk
Then i got ... already installed.

What can i do?

Yours kindly,

I suspect you have both JDK 8 and JDK 11 installed. Make sure that JDK 11 is the default JDK on your system. I don't know about Fedora - but on Ubuntu you could use update-java-alternatives for this.

Thank you for the reply.
Indeed on Fedora, you can change the "default" Java version with:
$sudo alternatives --config java.
When starting the server, it is not complaining about Java version anymore.
But now I get errors about my configurations file.

Is there a "default" config file I can download for Neo4j 4.0 to replace the current one in Use?
Yours kindly

With the installation there is a conf file included: /etc/neo4j/neo4j.conf.rpmnew
This is the file which belongs to 4.0 version.
After mv the current file in $mv sudo /etc/neo4j/neo4j.conf /etc/neo4j/neo4j.conf.old
renamed $sudo mv /etc/neo4j/neo4j.conf.rpmnew /etc/neo4j/neo4j.conf.
After this the server starts again.
