Change the default JSR-303 validator used by the configuration
properties binder so that it's initialized in a background thread.
This change allows the context to carry on loading additional beans
whilst the validator is initializing.
Fixes gh-11412
Update the `PropertyMapper` interface to return arrays rather than
Lists. Since implementations are package-private it's possible for us
to control how they are used and it helps to save a little memory.
Fixes gh-11411
Update the `LaunchedURLClassLoader` used for fat jar support so that
each iteration on a `findResources` result also allows for fast
exceptions.
Fixes gh-11406
Refactor fat jar loader classes so that less `char[]` instances are
created. This is primarily achieved by adding a new `StringSequence`
class that can chop up Strings without needing to copy the underlying
array. Since Java 8, calls to `String.subString(...)` always copy the
underlying char array. For many of the operations that we need, this
is unnecessary.
Fixes gh-11405
Remove support for the `__` environment variable list shortcut in order
to reduce complexity. The shortcut was developed before the new `Binder`
code was fully formed and isn't really necessary now since comma-lists
can be converted automatically.
Fixes gh-11410
Prior to this change, the Spring MVC auto-configuration would add a new
formatter to convert `java.util.Date` to/from `String` using the
configured configuration property `spring.mvc.date-format`.
This commit adds a new `WebConversionService` class that registers
date formatters with a custom date format, or register the default ones
if no custom configuration is provided.
This avoids duplicating equivalent formatters in the registry.
With this change, date types from `java.util`, `org.joda.time` and
`java.time` are now all supported.
This commit also replicates this feature for WebFlux applications by
adding a new `spring.webflux.date-format` configuration property.

This commit improve the couchbase health indicator to list the available
nodes. Doing so improves the reliability of the indicator as accessing
the bucket forces a remote call and better detect the cases where the
broker is down.
Closes gh-7369
