For those running applications on Java 8, dependency management for the
Java 8-compatible artifact is also provided.

Previously, Bitronix's server ID was hard-coded to be
spring-boot-jta-bitronix. This created the possibility of multiple
transaction managers performing recovery on each other's behalf as
they would be unable to identify their own XIDs due to the common
server ID.

This commit reinstates the default (which is the IP address of the
machine on which Bitronix is running), and introduces a new
property, spring.jta.transaction-manager-id, that can be used to
configure the id for both Atomikos and Bitronix. A cautionary note
has also been added to the documentation for Atomikos and Bitronix
explaining the need to configure this property.

Spring 4.2 has a @TestPropertySource which has some of the features of
@IntegrationTest. This change adds @TestPropertySource to the @IntegrationTest
annotation, so that (for instance) the cache key for the context includes
properties for the test.

Since @IntegrationTest has slightly different semantics I do not propose to
deprecate it. Users can use it or @TestPropertySource, the main difference being that
with @IntegrationTest the Spring Boot context loader is aware of the annotation
and it will set sensible defaults for server.port and spring.jmx.enabled.

There are some reflection hacks to overcome the usual fortifications of Spring Test.

Spring 4.1 has added support for XML HTTP message conversion using
Jackson. This was resulting in the response being sent back as XML
rather than JSON. Jackson's XML support doesn't cope well with lists
when it's being asked to deserialize to a Map [1] which is what the
test was doing.

This commit updates the test to indicate that it only accepts
application/json, thereby ensuring that the response can be correctly
deserialized into a Map.

Maven is configured to run tests found in classes ending in Tests.
This meant that the tests in BasicErrorControllerIntegrationTest (note
the missing s) were not being run.

This commit renames the test class so that it's picked up by Maven.

Previously, the CLI did not keep track of a dependency's users. This
meant that installing two extensions with a common dependency and
then unistalling one extension would break the other extension as the
common dependency would be deleted:

 1. Install a that depends on c
 2. Install b that depends on c
 3. Uninstall b
 4. a is now broken as c has been deleted

This commit updates the CLI to maintain a count for each artifact
that's installed into /lib. An artifact is now only deleted when the
count reaches zero.

As part of this change the code has been
extensively refactored to bring the structure into line with other CLI
commands and to improve testability.

Previously, Spring Data’s web support was auto-configured as part of the
JPA repositories auto-configuration. However, Spring Data’s web support
isn’t dependent on the use of Spring Data JPA or even repositories.

This commit moves the auto-configuration into a standalone class, making
it independent of the use of Spring Data JPA and Spring Data
repositories.

Windows absolute paths cannot be processed by the CLI compiler, so the install
command wasn't working on Windows. This change converts ths path to a URI first
and then it works as a Spring Resource.

JerseyAutoConfiguration is annotated with @ConditionalOnClass. It
references both SpringComponentProvider.class and
ServletRegistration.class. Normally, this wouldn't be a problem as, in
the absence of either of those classes, the configuration class bean
will not be present in the bean factory and, therefore, its
annotations will never be introspected using reflection.

However, JerseyAutoConfiguration is a WebApplicationInitializer. This
means that when it's deployed to a standalone container,
JerseyAutoConfiguration is found by the container and its class is
passed to SpringServletContainerInitializer.
SpringServletContainerInitializer introspects every
WebApplicationInitializer class so that it can order them. This blows
up if Jersey's SpringComponentProvider class isn't on the classpath as
the annotation is referencing SpringComponentProvider as a Class and
the attempt to load it fails. The problem can be avoided by
referencing SpringComponentProvider using a String.
