Launching LibreOffice fails on fat clients

[fottsia]

Launching LibreOffice on Ubuntu 18.04 succeeds on thin clients but fails on fat clients with the following:

javaldx: Could not find a Java Runtime Environment!
Please ensure that a JVM and the package libreoffice-java-common
is installed.
If it is already installed then try removing ~/.libreoffice/3/user/config/javasettings_Linux_*.xml
Warning: failed to read path from javaldx
