My Java enviroment is IBM Java 8:

    JCL - 20171113_01 based on Oracle jdk8u151-b12

Any idea how to fix the problem? Thanks

My solution was to remove the other Java-JREs and installed the default-jre (Java 8) package instead. After that, it worked.

If you try this?   ./rapidminer-studio/RapidMiner-Studio.sh this work for me.
