Previously, when access logging was enabled and the management server
was running on a separate port, both the main server and the management
server would write their access logs to the same file. Having two
separate containers writing to the same file could cause problems such
as causing log rotation to break.
This commit updates the actuator so that when the management server is
running on a separate port (and therefore using a separate container)
it prepends management_ to the access log prefix so that the main
server and the management server write their access logs to separate
files in the same directory.

Allow an instance of StatsDClient to be injected into the StatsdMetricWriter
which is used for exporting metrics to a Statsd server. This new constructor
allows the client to be injected but does not change the default behavior of
the writer.
Previously, auto-configuration of the Flyway and Liquibase endpoints
would fail if there were multiple Flyway or Spring Liquibase beans
in the application context.
This commit updates them so that they are now conditional on a single
candidate.

Commit b02aba4 has renamed `management.security.role` to
`management.security.roles`. Unfortunately, the `HealthMvcEndpoint`
was still looking at the old property.
This commit makes sure that the proper key is used and any custom
role is applied rather than an unconditional `ADMIN` role.

Call afterPropertiesSet on the delegate `ResourceHttpRequestHandler`

Previously, MetricExportAutoConfiguration consumed
ExportMetricWriter-annotated GaugeWriter beans in its constructor and
also produced such a bean from one of its @Bean methods. This cycle
caused a BeanCurrentlyInCreationException to be thrown when the
bean method was active (the spring.metrics.export.statsd.host property
was set).
This commit break the cycle by moving the bean method into a separate,
nested configuration class. It also updates the existing test for
auto-configuration of a Statsd writer to catch any possible cycles
and to verify that the writer has be registered with the
MetricsExporter.

Previously, a NullPointerException would occur if
endpoints.docs.curies.enabled was true and the default value was being
used for either server.port or management.port.
EndpointWebMvcHypermediaManagementContextConfiguration has been
restructured to ensure that the DocsMvcEndpoint bean is defined before
the condition on its existence is evaluated. Previously this was
dependant on the class’s bean methods being processed in a particular
ordering, something that would be ok when using ASM but would vary when
using reflection.

The MBean requires that a file does not exist at the location to which
it’s dumping the heap. This commit updates the test to ensure that the
temporary file that’s created to get a location for the heap dump file
is deleted before asking the MBean to dump the heap to that location.
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

Previously, the shutdown endpoint would spawn a new thread to perform
the shutdown but did not explicitly configure its thread context
class loader (TCCL). This mean that the new thread would use the
request thread's TCCL as its TCCL. This meant that a different TCCL
would be used compared to a shutdown triggered by the shutdown hook
and also caused problems with Tomcat's thread leak detection logic.
This commit updates the shutdown endpoint to explicitly configure the
TCCL of the shutdown thread to be the ClassLoader that loaded the
endpoint's class.

Where possible, code that previously synchronized on this (or on the
class in the case of static methods) has been updated to use an
internal monitor object instead. This allows the locking model that's
employed to be an implementation detail rather than part of the
class's API.
Classes that override a synchronized method continue to declare
the overriding method as synchronized. This ensures that locking
is consistent across the superclass and its subclass.

When a custom management.port is used, the child context is configured
with an EmbeddedServletContainerFactory bean that has the same class
as the parent context’s EmbeddedServletContainerFactory bean. This
ensures that the child context uses the same type of embedded container
as its parent when there are multiple embedded containers on the
classpath. It also causes a failure when the custom
EmbeddedServletContainerFactory subclass cannot be instantiated, for
example because it’s an anonymous inner-class.
This commit improves the diagnostics so that we fail fast with an
information exception message when we detect that the embedded servlet
container factory bean’s class cannot be instantiated.

This commit changes the default version of Tomcat to 8.5.3 while
also retaining support for Tomcat 8.0 and 7.0. The main difference
in 8.5 is that the ServerSocketFactory abstraction that allowed the
TrustStore and KeyStore to be configured programatically no longer
exists. This logic has been replaced with the use of a custom URL
protocol (springbootssl) that provides access to the key store and
trust store of an SslStoreProvider. In addition to working with 8.5,
this approach has the advantage of also working with 8.0 and 7.0.

This commit adds `@AliasFor` meta-data to annotations that declare an

Previously, if the `contextPath` of the application wasn't the root, the

Previously, SimpleInMemoryRepository used a ConcurrentReferenceHashMap
to store its locks. The type of map will discard its entries when the
JVM comes under GC pressure. With the code in its previous form, this
could lead to a NullPointerException when the following occurred:
1. putIfAbsent returned null indicating that a new entry has been added
to the map
2. GC pressure caused the map to discard the new entry
3. get returned null as the entry has been discard
There are two problems with the existing code:
1. Its usage of a ConcurrentMap is incorrect. The correct usage is:
a. Call get to see if the map already contains a lock
b. If the lock is null, create a new one
c. Call putIfAbsent to add the new lock
d. If the return value is non-null, another thread has created the
lock and it should be used. If the return value is null, use the
new lock created in b.
2. Once the use of ConcurrentMap has been corrected, the fact that it is
a ConcurrentReferenceHashMap means that different threads could
access the same value using different locks. This would occur if one
thread has retrieved a lock from the map and is using it, while GC
causes the lock to be removed from the map. Another thread then
attempts to get the lock and, as GC pressure has remove it, a new
lock is created allowing concurrent access to the same value.
This commit updates the code to use the ConcurrentMap correctly and also
replaces the ConcurrentReferenceHashMap with a ConcurrentHashMap. This
means that the repository will now use slightly more memory but this is
outweighed by the benefits of thread-safe updates and no risk of an NPE.

"Starter POM" is a confusing term as it implies the starter may be a

reduce the confusion (especially in the way such starter should be
declared in the build), the term Starter POM has been renamed to Starter.

Update EndpointWebMvcAutoConfiguration so that ApplicationFailedEvents
cause the management context to close.
Prior to this commit if an application failed to start (for example
because `server.port` was already in use) the management context would
remain open and the application would not exit.

This commit improves the `InfoContributor` infrastructure as follows:
* `InfoEndpoint` no longer breaks its public API and returns a Map as
before
* `Info` is now immutable
* All properties of the build are now displayed. Since we control the
generation of that file, there is no longer a mode to restrict what's
shown
* Build info is now generated in `META-INF/build-info.properties` by
default

Reorganize web related classes for better separation of concerns.
Mainly this involves moving classes from `o.s.b.context.embedded`
that aren't directly tied to embedded servlet containers to
`o.s.b.web` and relocating everything from `o.s.b.context.web`.
