Instead of always creating a new ElasticSearch client, we now check for
the presence of a custom bean configuration and use that if it's
available.

Update the Eclipse product setup so that `checkout.location` is stored
as a workspace variable. Without this things get mixed up when trying
to run different installations for different branches.

Update Eclipse settings to make use of a custom Spring formatter
implementation. Using a custom formatter allows us to fix a couple of
issues with the version that shipped with Eclipse Mars.1 (Eclipse bugs
The custom formatter also means that it is possible to use Groovy
Eclipse despite the fact that it has formatter regressions (see
https://github.com/groovy/groovy-eclipse/issues/142).

The `deprecated` attribute is deprecated as of Spring Boot 1.3 and
replaced by the `deprecation` object. Any IDE relying on the previous
structure still expects the `deprecated` attribute though.
The annotation processor is adding that information automatically when it
merges manual content so it is not necessary to define that attribute in
the source.

Previously, JarFileArchive would always unpack any entries marked for
unpacking to ${java.io.tmpdir}/spring-boot-libs. This could cause
problems if multiple Spring Boot applications were running on the same
host:
- If the apps are run as different users the first application would
create the spring-boot-libs directory and the second and subsequent
applications may not have write permissions to that directory
- Multiple apps may overwrite each others unpacked libs. At best this
will mean one copy of a jar is overwritten with another identical
copy. At worst the jars may have different contents so that some of
the contents of the original jar disappear unexpectedly.
This commit updates JarFileArchive to use an application-specific
location when unpacking libs. A directory beneath ${java.io.tmpdir} is
still used but it's now named <jar-file-name>-spring-boot-libs-<uuid>.
A loop, limited to 1000 attempts, is used to avoid problems caused by
the uuid clashing.

Prior to this commit, EmbeddedWebApplicationContext would perform its
close processing and then stop the embedded container. This could
lead to the closed context's dispatcher servlet handling an HTTP
request and refreshing the context again. This opened up two
possibilities that we need to avoid:
1. Another HTTP request could be received by the dispatcher servlet
while the context is still being refreshed. This could lead to the
context being used before its refreshed. I believe this could be
the cause of the current modification exception described in
gh-3239 and SPR-13123.
2. It can lead to a race during shutdown as the shutdown hook's
attempt to close the context races with the refresh initiated by
the HTTP request. This is possible as the shutdown hook bypasses
the sychronization on startupShutdownMonitor that would normally
prevent refresh and close from occurring in parallel. This race
can lead to a deadlock as described in gh-4130
Closes gh-4130
Spring HATEOAS’s DummyInvocationUtils, that is used by
ControllerLinkBuilder, uses Objenesis. By default, Objenesis caches
the instances that it creates and uses the class name as the cache key.
This is problematic when DevTools’ restart support is enabled as the
class loader changes with each restart and ClassCastExceptions occur
due to Objenesis returning a cached instance that was created by an
old restart class loader.
This commit works around the problem described above by auto-configuring
a bean that uses reflection to replace DummyInvocationUtils’ default
Objenesis instance with one that has caching disabled.

Previously, if Solr 5 was on the classpath, SolrAutoConfiguration
would fail with a rather cryptic error message due to a change in the
inheritance hierarchy of CloudSolrServer between Solr 4 and Solr 5.
This commit updates SolrAutoConfiguration to be conditional on a
class that exists in Solr 4 but was removed in Solr 5. This has the
effect of switching off the auto-configuration when Solr 5 is on
the classpath, allowing the auto-configuration report to be used to
identify why the configuration was disabled. The documentation has
also been updated to state that Spring Boot does not currently support
Solr 5.0.
Closes gh-2795
This commit adds a new property, logging.register-shutdown-hook, that
when set to true, will cause LoggingApplicationListener to register
a shutdown hook the first time it initializes a logging system. When
the JVM exits, the shutdown hook shuts down each of the supported
logging systems, ensuring that all of their appenders have been
flushed and closed.
Closes gh-4026
This commit changes the new mode-based configuration to use two new
methods – setBannerMode on SpringApplication and bannerMode on
SpringApplicationBuilder. The old methods, setShowBanner and
showBanner on SpringApplication and SpringApplicationBuilder
respectively, have been reinstated and deprecated.
Closes gh-4001
This commit adds the option to output the banner using the logger
instead of standard out. Rather than taking a boolean
spring.main.show-banner is now configured using an enum. Three values
are supported:
- LOG: the banner is logged
- CONSOLE: the banner is printed to standard out (previously true)
- OFF: the banner is switched off (previously false)
The default behavior remains unchanged; the banner will be printed to
standard out.
Closes gh-4022

Default will extract an "authorities" key from the map coming from the
server. No existing servers I am aware of actually send that data, but
it might be helpful as a default nevertheless. User can override the
default by adding a bean of that type.
Fixes gh-3711
