Observed Behavior:
The following message is repeatedly displayed in the logs:

Resolución/Solución alternativa: This is because Java 8 needs write access to a directory.
To fix it:

Preferred: add the directory to the bbuser home directory:

mkdir /home/bbuser/.java/.systemPrefs
chown bbuser /home/bbuser/.java/.systemPrefs

OR give bbuser ownership of the java system level version of it:

chown -R bbuser /etc/.java/.systemPrefs
