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
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
Fixes gh-4313
See gh-2611
Previously, one SpringApplicationAdminMXBeanRegistrar was created
per context. When there was more then one context this would result
in a javax.management.InstanceAlreadyExistsException being thrown
as an attempt was made to register the MBean more than once.
This commit updates SpringApplicationAdminJmxAutoConfiguration so
that the registrar is only created when there's no such existing bean
in the context hierarchy.
Closes gh-6378
ConcurrentHashMap implements `containsKey` with `get`. By removing a
redundant call to `containsKey`, we guarantee better performance in our
counter services.
The geek inside measured this with JMH, and found under 4 threads of
contention, throughput on this check was 40% higher in success case.

Previously, if there was a hierarchy of SpringApplications, the admin
MBean would report that the application was ready as soon as any
application in the hierarchy was ready. This could lead to a client
trying to query a property in the environment before it's available.
This commit updates the MBean registrar to that the MBean only reports
that the application is ready when the context that contains the
registrar has refreshed and fired its ApplicationReadyEvent.
Closes gh-6362
