Previously, if a call to doFilter in MetricFilter failed (i.e. it threw
an exception), it would be handled as if it had a response status of
200. This is because the servlet container was yet to handle the
exception and set the response status to 500.

This commit updates MetricFilter to assume that an exception thrown from
doFilter will result in a response with a status of 500. Strictly
speaking, even though the filter has highest precedence and will
therefore run last on the way back out, this may not always be the case.
For example, a custom Tomcat Valve could handle the exception and result
in a 200 response but that’s an edge case that’s into shooting yourself
in the foot territory.

Hibernate depends on antlr:antlr:2.7.7 (the latest version on Antlr 2)
and fails with earlier 2.7.x versions due to a missing method. This
can cause problems for Maven users if they also depend on something that
pulls in an earlier version of Antlr, such as
spring-boot-starter-velocity. Gradle users are unaffected as, when
multiple versions of a dependency are found in the graph, Gradle will
choose the latest version.

This commit adds dependency management for antlr:antlr:2.7.7 to ensure
that the latest, and Hibernate compatible, version of Antlr 2 is used.

When reverse==false we have to be careful to remove the right element
when capacity is reached.

Default to true (so existing apps change their behaviour, but that
seems to be the majority vote).

Previously GsonHttpMessageConvertersConfiguration was unconditional
with its nested configuration class being
@ConditionalOnClass(Gson.class). This led to the unnecessary
registration of the GsonHttpMessageConvertersConfiguration bean when
Gson isn't on the classpath.

This commit moves the condition up onto the outer class so that no
Gson-related beans are created when Gson is not on the classpath.

Closes gh-2778

Closes gh-2788

Closes gh-2787 (I hope)

This commit improves upon the changes made in a8bf9d34 by adding
support for relaxed binding of the endpoints.enabled and
endpoints.<name>.enabled properties. This is achieved by replacing
use of @ConditionalOnExpression (which does not support relaxed
binding) with a custom condition implementation that uses
RelaxedPropertyResolver.

Closes gh-2767

Closes gh-2779

Previously, only invocations of /metricName/ would honour the enabled
property and return a not found (404) response. For endpoints which
support nested paths, access to /metricName/foo would ignore the enabled
flag and return an OK (200) response. Furthermore, there was a comment
in EndpointMvcAdapter that suggested that an endpoint shouldn’t be
called when it is disabled, however this was not the case.

This commit updates EndpointWebMvcAutoConfiguration and
JolokiaAutoConfiguration to only register their MvcEndpoint beans if
the underlying endpoint is enabled. This means that an
EndpointMvcAdapter should not be called if its delegate is disabled,
making the comment described above accurate.

The check for the delegate being enabled has been retained so as not to
rely upon the auto-configurations’ behaviour. The methods which handle
nested paths (MetricsMvcEndpoint.value() and
EnvironmentMvcEndpoint.value()) have been updated to add the same check
for the enablement of their delegate.

This reverts commit 3a22443f.

Add a note to the logging documentation to point out a potential gotcha.

Fixes gh-2709

The property in XADataSourceAutoConfigurationTests should be
`data-source-class-name`. Previously the `-name` was missing.

Update RelaxedDataBinder so that multiple overlapping nested property
names can be bound to a Map.

Prior to this commit, properties of the following form could not be
bound to Maps:

  foo: baz
  foo.bar: spam

This was due to BeanWrapperImpl throwing an InvalidPropertyException
when binding `map[foo][bar]` because `foo` is already bound to `baz`.

The updated code now detects such cases and instead uses the binding
property `map[foo.bar]`.

Fixes gh-2610

Closes gh-2723

Tomcat uses the strings “on” and “off” to enable and disable
compression. YAML interprets on as true and off as false, leaving
ServerProperties.Tomcat.compression configured with “true” and “false”
respectively. One solution is to use “on” rather than on and “off”
rather than off in the YAML file but users may not realise that they
need to do so.

This commit updates the connector customiser that configures compression
to map “true” to “on” and “false” to “off”.
