Add AssertJ as a managed dependency and also include it in
spring-boot-starter-test. Also provide a simple adapter class to allow
Hamcrest matchers to be used as AssertJ Conditions.
Fixes gh-5048
Update DataSourceAutoConfiguration so that pooled datasource
configurations are only loaded via an @Import. If left as nested
classes, the load order is JVM specific and can result in the wrong
configuration being loaded.

Previously, the Launcher was creating a new runner thread that would
call the application's main method. An exception thrown by this thread
is handled differently to one thrown by the JVM's main thread leading
to different exit behaviour. Furthermore, the separate thread isn't
actually necessary.
This commit removew the use of a separate runner thread from the
Launcher. This means that the JVM's exit behaviour will be consistent
and also removes the overhead of createing a starting an extra thread.

Previously, BeanDefinitionLoader declared a field of type
GroovyBeanDefinitionReader which is a GroovyObject subclass. This is
problematic as BeanDefinitionLoader is always loaded but Groovy is an
optional dependency. Even on a JVM where class verification is performed
lazily, this can still cause problems if something reflectively tries
to access the class’s declared fields. On a JVM where classes are
verified at load time, it would be impossible to start a Spring Boot
application without having Groovy on the classpath.
This commit changes the field to be a BeanDefinitionReader, removing
the indirect reference to GroovyObject form BeanDefinitionLoader’s
signature. The reader is downcast to a GroovyBeanDefinitionReader in the
body of a method body that will only be invoked when Groovy is on the
classpath.

Update SpringBootJoranConfiguratorTests to ensure that logback
is left in a sane state. Prior to this commit, running all tests
in eclipse would fail due to ErrorPageFilterTests expecting
specific log output.
Previously, Spring Boot mapped both `DataSourceProperties` and the actual
`DataSource` implementation to the same prefix. This results in a huge
amount of keys in the `spring.datasource` namespace with no way to
identify those that are valid for the pooled data source in use.
This commit maps the four pooled data sources we support in four isolated
namespace, keeping `spring.datasource` only for the common settings.
These are `spring.datasource.tomcat`, `spring.datasource.hikari`,
`spring.datasource.dbcp` and `spring.datasource.dbcp2` for the Tomcat,
Hikari, Commons DBCP and Commons DBCP2 implementations respectively.
Closes gh-2183
Spring Boot fires event very early in the application lifecycle and we
should make crystal clear that a regular `@Bean` registration cannot be
used to register a listener on them.
Closes gh-5061
Ensure that JarFile caches are cleared once the ApplicationContext has
loaded. Caches are cleared manually with the assumption that no
further class loading is likely.
Closes gh-4882
Refactor `spring-boot-loader` to reduce the amount of memory required
to load fat & exploded jars. Jar files now no longer store a full list
of entry data records, but instead use an array of entry name hashes.
Since ClassLoaders often ask each JAR if they contain a particular
entry (and mostly they do not), the hash array provides a quick way to
deal with misses. Only when a hash does exist is data actually loaded
from the underlying file.
In addition to the JarFile changes, the Archive abstraction has also
been updated to reduce memory consumption.
See gh-4882
Remove the use of JDK loggers in Launcher and PropertiesLauncher to
ensure allow the custom Log4j2 `LogManager` to be used with Spring Boot
applications.
Fixes gh-3815
Add SharedMetadataReaderFactoryContextInitializer to ensure that a
shared caching MetadataReaderFactory is used between configuration
classes and auto-configure sorting.
Fixes gh-4993
This commit enables the use of // @formatter:off and // @formatter:on
to surround lines of code that should not be formatted. It also adds
a code template that can be used to quickly wrap the selected lines
of text with the off and on comments.
