* ServletContextInitializer-patch-1:
  Fixed ServletContextInitializer documentation

Closes gh-6410

* Spring-AMQP-1.6.1:
  Upgrade to Spring AMQP 1.6.1.RELEASE

Closes gh-6414

Update Log4J2LoggingSystem so that the FILTER is applied to the main
configuration and not to the root logger. Prior to this commit calls
to `logger.isErrorEnabled()` would not consider the filter and hence
would always return `true`. This caused `SpringApplication` to silently
swallow exceptions.

Fixes gh-5271

Closes gh-6415

Update PropertySourcesPropertyValues so that source detection logic for
collection values also considers complex types. Prior to this commit
properties of the following form were processed correctly:

	PropertySource-A
	  list[0]=x

	PropertySource-B
	  list[0]=y
	  list[1]=z

But properties of the form were not:

	PropertySource-A
	  list[0].name=x

	PropertySource-B
	  list[0].name=y
	  list[1].name=z
