Update the executable JAR `Handler` to fallback to the JVM handler if
the jar cannot be opened. This prevents exceptions when trying to
open URLs in the form "jar:jndi:/localhost...".

Fixes gh-347

Fix ConfigFileApplicationListener to correctly bind
`application.properties` to SpringApplication. Binding in RC2 failed
due to the fact that `ConfigurationPropertySources` did not extend
`EnumerablePropertySource`.

Fixes gh-346

Rename EnvironmentDelegateApplicationContextInitializer to
DelegatingApplicationListener and EnvironmentDelegateApplicationListener
to DelegatingApplicationListener.

Reintroduce ConfigFileApplicationContextInitializer for tests that
wish to reuse 'application.properties' configuration.

Fixes gh-344

Improve package structure and include package-info javadoc.

This reverts commit 89283e46.

Revert until we can find a new home, outside of the usual build
process.

Fix ConfigFileApplicationListener to load profile specific files
(*-profile.ext) both as a root document, and again with the profile
active.

This allows profile specific files to still include a 'spring.profiles'
property if they wish.

Issue: gh-340

Run with "mvn spring-boot:run" and then scrape the Markdown from stdout.
(Result already added to docs/autoconfig.md.)

Update AbstractRepositoryConfigurationSourceSupport to use the newly
introduced RepositoryConfigurationDelegate instead of effectively
reimplementing Spring Data Commons functionality which was prone to
changes in the API (code that wasn't considered to be API in the first
place).

Switch from implementing BeanClassLoaderAware to ResourceLoaderAware
to avoid having to set up a DefaultResourceLoader which should also
improve IDE integration.

Fixes gh-236

Older versions of JBoss AS have a classpath clash with an older
SLF4J (pre 1.6.5), so to prevent an app from blowing up on
startup we defensively catch a NoSuchMethodError.

Fixes gh-339

Locate PropertySourcesLoaders using SpringFactoriesLoader and refactor
the interface to expose file extensions and support 'profiles' within
documents.

Rework ConfigFileApplicationListener for consistent profile loading.
Profiles are now loaded in a consistent order for both profile specific
files, and contained profile documents (i.e. YAML sub-sections).

Also update ConfigFileApplicationListener so that it no longer directly
processes @ProperySource annotations. Instead the standard Spring
ConfigurationClassPostProcessor will insert @PropertySource items with
ConfigFileApplicationListener later re-ordering them.

The SpringApplication can no longer be configured using @ProperySource
annotations, however, application.properties may still be used.

Fixes gh-322

Update ConfigFileApplicationListener so that custom names and custom
locations use consistent ordering. i.e. earlier items take precedence
(same as @ProperySource).

Add "my.property" to `application.properties` in order to test ordering
or property sources.

Also use hamcrest for assertions.

Update javadoc to consistently use the "code" style with <pre> blocks.
Also include the latest spring-javadoc.css formatting file.

Fixes gh-332

Change `EmbeddedWebApplicationContext` to no longer automatically call
`registerShutdownHook()`. Shutdown hooks must now be registered by the
caller (for users of SpringApplication this will happen automatically).

Fixes gh-314

* pull336:
  Now custom SpringApplication class can be used when extending SpringApplicationContextLoader

Previously the core Spring processing of @PropertySource would
resolve placeholders in the location attribute, but the pre-loading
of the property source by Spring Boot didn't do that. Now implemented
using Environment.resolvePlaceholders() (N.B. at a time when the only
Environment entries available are system properties and OS env vars).

E.g.

	@Configuration
	@PropertySource("classpath:/${source.location}.properties")
	protected static class WithPropertySourcePlaceholders {
           ...
	}

When binding a nested map structure, RelaxedDataBinder pre-populates
the target object with default empty maps. Previously, when these
structures overlapped, each step in pre-population process could
potentially overwrite what had come before it. This led to the output
of the pre-population process being incomplete which would lead to a
binding failure.

This commit updates the pre-population process so that it checks to see
if a property's value has already been set by an earlier step in the
process. If it has been set, the existing value is now reused rather
than being overwritten by a new empty map.

Fixes #328

Previously, the Gradle plugin would package all of a project's
dependencies in the jar's lib directory, irrespective of each
dependency's type. This led to non-jar artifacts being packaged in
the lib directory where only jar dependencies are expected. See #334
for an example failure.

This commit updates the Gradle plugin such that it only packages
dependencies of type jar, ejb, ejb-client, test-jar, or bundle. This
brings the Gradle plugin into line with the Maven plugin.

Fixes #334.

Ignore JMS sample which intermittently fails to run on CI.

See gh-323

Update the `ArtifactsLibraries` used by the maven plugin to filter
based on artifact types. This prevent `.pom` files from accidentally
being packaged in `/libs` and ultimately resulting in 'Unable to find
ZIP central directory records' errors.

Fixes gh-324

Revert commit a97bcfe3 as adding
profiles automatically may be problematic.

Updates gh-296

* gradle-mainclass:
  Add mainClass option for Repackage task

Add `mainClass` property option to the Repackage task. If the property
is defined within a task, it works in the same way as if it defined
within the springBoot{} 'ext' properties section.

Option is valid only for that specific task where it is defined, and
will override option defined in springBoot{} ext properties.

Fixes gh-283

* patch-1:
  Prevent 404s in README.md links

Fix links to ensure that they don't cause 404 errors when published to
Github Pages.

Fixes gh-304
