Due to gradle/gradle#5510, using a lambda for a task action breaks
up-to-date checks in certain circumstances.

This commit updates JavaPluginAction to use an inner-class in place
of a lambda for the action that it adds to JavaCompile tasks. A test
has not been added as it does not appear to be possible to reproduce
it with a TestKit-based test.

If the web application type is set via properties,
it is available only after binding. The environment needs
to be converted to the appropriate type if it does not match.
If a custom environment is set, it is not converted.

The 3.0.1 version of the Maven Javadoc Plugin contains a bug [1] that
means that a link URL must redirect otherwise it is ignored.

[1] https://issues.apache.org/jira/browse/MJAVADOC-532

The -link parameters passed into the javadoc executable are used
as-is. For example, redirects are not followed. Unlike 3.x, 2.x of the
Maven javadoc plugin does not attempt to follow redirects before links
are passed to the javadoc executable. As a result, for external links
to work, the links that we provide must be canonical and produce a
200 response when accessed.

quite long.

Previously, the setter of a property whose second letter is upper-case (
such as `oAuth2Uri`) was not detected properly. The JavaBean spec states
that, in such a case, the first letter should not be capitalized (i.e.
the setter should be `setoAuth2Uri` rather than `setOAuth2Uri`).

This commit makes sure that Jackson uses standard bean names and fixes
the setter detection algorithm to take this case into account.

Prior to the changes that fixed #12451,
`FilteredPropertySources` and `CompositePropertySources` were required
by the `PropertySourcesDeducer` to ensure that configuration properties binding
could see changes to the environment even when there was a
PropertySourcesPlaceholderConfigurer in the context. #12451 changed the way
property sources are adapted by `SpringConfigurationPropertySources`, removing the
need for `FilteredPropertySources` and `CompositePropertySources`.
