Jersey 2 has some Spring support built in but it's a bit awkward to
use in a Boot app, so autoconfiguration seems appropriate. The tests
and sample show how to use it, but the short story is that any
@Component can define JAX-RS endpoints via @GET etc.

There's a sample for Jersey 1 as well (pay careful attention to
the plugin configuration if you want to build an executable jar)

Previously JacksonAutoConfiguration and GsonAutoConfiguration were
not actually auto-configuration classes. They were only processed
due to being imported by HttpMessageConvertersAutoConfiguration.
In addition to being misleadingly named, this meant that they could
not be included or excluded individually and were also tightly coupled
to HTTP message conversion.

This commit updates spring.factories to make both
JacksonAutoConfiguration and GsonAutoConfiguration actual
auto-configuration classes. As a result, they can now be enabled or
disabled individually and are no longer coupled to HTTP message
conversion.

This adds support for Hibernate 4.2 again by loading the specific

Previously, the Gradle plugin’s ProjectLibraries produced a new library
for every file dependency, even if the dependencies where on the same
file. This would lead to a repackaging failure due to multiple
libraries having the same name.

This commit updates ProjectLibraries to treat file dependencies on the
same file as a single library, thereby resolving the name clash.

The file name can now be overridden at runtime with a System property or
environment variable named "PIDFILE" (or "pidfile").

Previously, Tomcat initialization would only log the port of the
primary connector and would omit the scheme, whereas once Tomcat was
started the port of every connector and their schemes would be logged.

This commit makes things symmetrical by updating the logging performed
at initialization to include every connector's port and scheme.

During initialization the port number that the connector the has
been configured with is logged. This means that, if the connector has
been configured to bind to an free port, 0 will be logged. Once
Tomcat has started, the number of the port that the connector has
bound to is logged.

To make it easier to identify the source of the competing LoggerFactory
implementation, this commit updates the exception message to include

Without the @Param annotations, using either of the search URIs would
resulted in a 400 response and an error describing the lack of @Param
annotation.
