Run SAP GUI 7.50 on Ubuntu

SAP Pllatin GUI runs on Java. If you have installed the newest Java Java Release which is currently Java 11, SAP GUI will not work or at least have issues.

To solve this the following steps need to be done

• install the OpenJDK version of Java 8 *
• install JavaFX *
• intall Oracle JRE 8 *
• tell SAP GUI to use Java 8 instead of the newest version

To install use the following command

sudo apt install openjdk-8-jdk libopenjfx-java

Download and unzip the JRE 8 to /usr/lib/jvm/.

Now set the environment variable. Edit the user profile

gedit ~/.profile

and add the following line

export PLATIN_JAVA="/usr/lib/jvm/java-8-openjdk-amd64/bin/java"
export PLATIN_JAVA="/usr/lib/jvm/jre1.8.0_211/bin/java"

* unfortunately recently the JavaFX support for OpenJDK Java 8 has been removed from Ubuntu, therefore the simplest solution is to use Oracle JRE. Due to licensing changes this version is for productive use not free any more.
