Make build pass on JDK11, fix javadoc configuration

Descriptions of the changes in this PR:

### Motivation

Build fails on recent JDK11 versions and on JDK11, see #2133, this is because javadoc has problems with references to core Java API when source version is set to 8.

### Changes
Upgrade Java doc plugin to latest 3.1.1 and disable auto linking to core Java classes with
`<detectJavaApiLink>false</detectJavaApiLink>
`
Closes #2133
