The javadoc generation fails when using JDK 11 with:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-javadoc-plugin:3.0.1:javadoc (javadoc) on project narayana-full: An error has occurred in Javadoc report generation:
[ERROR] Exit code: 1 - /home/jenkins/workspace/narayana/PROFILE/CORE/jdk/jdk11.latest/label/linux/ArjunaCore/arjuna/classes/com/arjuna/ats/internal/arjuna/objectstore/slot/PmemSlots.java:24: error: package io.mashona.logwriting does not exist
[ERROR] import io.mashona.logwriting.ArrayStore;

I tested a "fix" that ignores javadoc errors and also removes the provided scope on the io.mashona:mashona-logwriting:1.0.0.Beta1 dependency (presumably because it's not provided by JDK 11).

I will raise a PR with that change in the hope that, during review, we can find a better solution.
