Links to Spring Framework missing from Javadoc

[jzheaux]

Related to #7868

A class that references objects in another Javadoc should link to that Javadoc. This worked in 4.2.12.RELEASE and onward, but stopped working again later on.

It can be fixed by configuring Javadoc links in the Gradle Javadoc class like so:

javadoc {
    options {
        links = [
            "https://dos.spring.io/spring/docs/$springFrameworkVersion/javadoc-api/",
            "https://docs.spring.io/spring-ldap/docs/$springLdapVersion/apidocs/",
            "https://docs.oracle.com/en/java/javase/11/docs/api/"
        ]
    }
}

Or programmatically in Groovy with an instance of StandardJavadocDocletOptions.
