'java.lang.NullPointerException: Cannot invoke "jdk.internal.platform.CgroupInfo.getMountPoint()" because "anyController" is null

I have an error when I'm trying to copy data from csv file into mysql database, but when I launch the temps.etl.xml file with java launcher, it gives me an error. I thank that this error occurs because of the csvConnection driver but I have no idea what to do to avoid it. THANK YOU for your help !!!!!

This is my code in temps.etl.xml

<!DOCTYPE etl SYSTEM "http://scriptella.org/dtd/etl.dtd">
<etl>
    <description>Copie des csv dans le data warehouse</description>
    <properties>
        <include href="connexion.properties"/>
    </properties>
    <connection id="db_out" driver="auto" url="$url" user="$user" password="$password" classpath="~/Scriptella/lib/mysql-connector-java-5.1.39-bin.jar" />
    <connection id="temps_csv_in" driver="csv" url="../data/temps.csv" />

    <query connection-id="temps_csv_in">
        <script connection-id="db_out">
            INSERT INTO temps(annee,mois,jour) VALUES (?annee,?mois,?jour);
        </script>
    </query>
</etl>

And the error message is :

Solution 1:[1]

I had a similar phenomenon with Spring Boot Actuator. In my case the problem was that the cgroup2 memory controller was missing for some reason.

The jdk.internal.platform.CgroupSubsystemFactory#create method expects a memory entry. You can check it with

$ cat /proc/cgroups

it should contain a row starting with "memory"

After a kernel update the problem was gone
