Error: Could not create the Java Virtual Machine (Ubuntu 18.04)

[yvig]

After installing processing, I tried to launch it and received this message

-Djava.ext.dirs=/usr/share/processing/processing-3.4/java/lib/ext is not supported. Use -classpath instead. Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit.
My java version was

anne@anne-Aspire-5810T:~$ java -version openjdk version "10.0.2" 2018-07-17 OpenJDK Runtime Environment (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.2) OpenJDK 64-Bit Server VM (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.2, mixed mode)
anne@anne-Aspire-5810T:~$ javac -version javac 10.0.2

I changed it in a Oracle one after reading in this page https://github.com/processing/processing/wiki/Supported-Platforms that "Due to incompatibilities, OpenJDK is not supported. "

Now my java version is
anne@anne-Aspire-5810T:~$ java -version java version "11.0.1" 2018-10-16 LTS Java(TM) SE Runtime Environment 18.9 (build 11.0.1+13-LTS) Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.1+13-LTS, mixed mode)
anne@anne-Aspire-5810T:~$ javac -version javac 11.0.1

but the problem remains.
