created war files. Exceptions were sometimes thrown when running on a
Linux NTFS mount.

Previously, DefaultRepositorySystemSessionAutoConfiguration would
read the local repository configuration from settings.xml, but did
not perform any property interpolation. This would leave placeholders
such as ${user.home} as-is and result in the use of the wrong
location. To address this, the code that reads settings.xml has been
updated to provide the current System properties as a property
interpolation source.

RepositoryConfigurationFactory configures the local repository as a
"remote" repository when the local repository location has been
overridden. This allows spring grab to copy dependencies from the
local repository into the grab output location (configured via the
grape.root system property) rather than having to download them again.
This logic did not consider the customization of the local repository
location via settings.xml so the dependencies would be downloaded again.
To address this, RepositoryConfigurationFactory has been updated to
attempt to use the location configured in settings.xml, before falling
back to the default location.

The logic that reads settings.xml has deliberately been duplicated. It
could have been extracted into a separate class, but this is only a
temporary measure until gh-3275 is tackled. Duplication was deemed
preferable to adding a new public class in 1.2.x that we’d then want to
remove in 1.3.

Create an EmbeddedVelocityToolboxView which supports loading toolbox.xml
files from the application classpath as well as the ServletContext. The
VelocityAutoConfiguration class has been updated to use the new view.

This change allows the `spring.velocity.toolbox-config-location`
property to work with embedded servlet containers.

Update EntityScanRegistrar so that multiple @EntityScan annotations can
be used with a single application. Previously, when an application used
multiple annotations only the first one found would get applied. This
changes alters that to augment the packages that will be scanned.

Update appendix example to use the more common `/var/log` folder rather
than `/var/logs`.

Previously, the VcapApplicationListener would discard any service
credential value that wasn't a String, Number, Map, Collection, or
null.  This was particularly a problem for services that exposed a
value as a JSON boolean.  This change takes booleans in the credential
payload into account, converting them to Strings so that they will
pass through the properties system properly.  There's no real downside
to this as Spring will coerce them back into Booleans if needed, by
the application.

AmqpAdmin does not require a CachingConnectionFactory. Using the more

Previously, spring.groovy.template.configuration.* was mapped onto both
GroovyTemplateProperties.configuration and GroovyMarkupConfigurer. The
former being a Map and the latter being specific type with getters and
setters. This clash caused problems with the IDE support.

GroovyTemplateProperties.configuration appeared to be dead code so it
was removed in 326bdf29. Unfortunately this broke the use of
spring.groovy.template.configuration.* properties as
GroovyTemplateProperties uses a prefix of spring.groovy.template and it
no longer had a configuration property.

This commit addresses the problem by updating GroovyTemplateProperties
to ignore unknown fields. This allows
spring.groovy.template.configuration.* properties to be used and bound
to GroovyMarkupConfigurer without reintroducing the clash which prompted
the initial change.

The build currently fails intermittently when an external container,
usually TomEE or Wildfly, fails to start within the default timeout
period of two minutes. This commit updates the timeout to 5 minutes for
all containers (Tomcat, TomEE and Wildfly) in the hope that it will
help to stabilise the CI build.

The JMS MessageListenerContainer supports the PlatformTransactionManager
abstraction with either a `JmsTransactionManager` for local transactions
or `JtaTransactionManager` for distributed transactions. The former is
kind of deprecated (`setTransacted` should be used instead). In any case,
any other `PlatformTransactionManager` implementation is not supported.

Update JmsAnnotationDrivenConfiguration to only associated a JTA
transaction manager, if any.

AuthenticationManagerBuilder.inMemoryAuthentication() as a
shared object in the HttpSecurity.
