* pull2181:
  Remove duplicate "should" word from README

Ensure that the system temp directory is passed to the Jetty
WebAppContext. This prevents `jsp` folders from appearing in the current
directory.

Fixes gh-2169

Update DispatcherServletAutoConfiguration to alias a MultipartResolver
that is not named correctly. This allows the DispatcherServlet to pick
up any MultipartResolver bean, regardless of its name.

See gh-2162

The `joda-time-jsptags.jar` jar file cannot be skipped.

Fixes gh-2168

Previously, no configuration properties were discovered on a class using
lombok instead of regular getters/setters.

This commit adds a support for some of the lombok annotations,
specifically that is @Data, @Getter and @Setter. Provides the same
semantic as what lombok is generating.

Closes gh-2114

* pull2165:
  Fix typo in tests

Ensure that the Maven plugin RunMojo attempts to detect the Spring
Loaded agent before deciding if the JVM should be forked.

Fixes gh-2140

Fix numerous copy-paste errors in EmbeddedServerPortFileWriter
where PID concepts are referenced.

Fixes gh-2161

Update HttpEncodingAutoConfiguration to ensure that the
CharacterEncodingFilter is ordered above any HiddenHttpMethodFilter.

Update LogbackLoggingSystem to protect against a potential null
CodeSource result.

Fixes gh-2149

Closes gh-2145

Update the file log pattern to write the thread name after the `---`
separator. The allows both file and console logs to be parsed in the
same way.

Fixes gh-2136

Update DefaultLogbackConfiguration to include OptionHelper.substVars
when setting the encoder pattern so that ${PID} is correctly expanded.

Fixes gh-2119

Refactor LoggingApplicationListener and LoggingSystem to restore
Spring Boot 1.1 logging behavior. The LOG_FILE and LOG_PATH system
properties are now set before configuring the logger.

The `logging.path` property is now once again optional and will not be
used when `logging.file` is specified. The documentation has also been
updated to reflect the changes.

Health indicator configuration keys have moved from the health.* to the
management.health.* namespace. This commit adds an explicit reference
to the previous location.

See gh-2128

Health indicator configuration keys have moved from the health.* to the
management.health.* namespace. This commit makes sure that these are
documented properly in 1.1.x as well.

See gh-2118

ManagementSecurityAutoConfiguration fully relies on the presence of a
web environment, yet the configuration class itself was not guarded by
`@ConditionalOnWebApplication` (while nested config where).

This turned out to be a problem for command-line applications using
spring security (i.e. CRaSH integration).

Fixes gh-2112

Previously, non camel case properties were wrongly resolved, i.e.
getFOO() leading to a 'f-o-o'. While unusual, underscores can also be
added to a property name. In that case, the hyphen should not be added
as the binder consider this to be a single "word". Typically setFoo_Bar
on the "something" prefix is mapped using "something.foo_bar".

All these cases are now handled properly, generating the target name that
the binder expects.

Fixes gh-2118

The method 'injectIntoSecurityFilter' added In 3c1e48c8 assumes that
Spring security is in the classpath so any management endpoints that are
deployed on a different port requires Spring Security all the sudden.

This commit separates the creating of the EndpointHandlerMapping in two
mutually exclusive @Configuration: one that is triggered if Spring
Security is not in the classpath and one that is triggered if Spring
Security is in the classpath. The latter apply the security filter in the
endpoint mapping if it exists.

Fixes gh-2124

The move of health.* keys to management.health.* broke them as they
are not defined as configuration keys and `ManagementServerProperties`
is strict on the whole management namespace.

This commit updates the tests to actually include that properties class
and relax the "ignoreUnknownFields" condition so that extra attributes
can be defined on the "management" namespace.

Fixes gh-2115
