This commit fixes the `responseCommitted` test in
`DefaultErrorWebExceptionHandlerIntegrationTests` and reworks the whole
test class to use the `ContextRunner` infrastructure.
Fixes gh-11519
This commit removes
`RestTemplateBuilder.requestFactory(ClientHttpRequestFactory factory)`
because it can be misleading. This builder class is meant to be
immutable, but calling that method and then timeout related ones will
affect the `ClientHttpRequestFactory` instance.
Instead, this method is replaced with a
`Supplier<ClientHttpRequestFactory>` that is called every time a
`RestTemplate` is being built.
That approach may reduce the reusability of request factories, but it is
much more consistent.
Closes gh-11255
This commit adds a javadoc note about a usability issue described in
gh-11255. While `RestTemplateBuilder` is an immutable class, providing a
custom instance of request factory and deriving several
builders/templates from that point may have some unexpected behavior,
since that instance is shared amongst builders instances.
This issue is fixed in Spring Boot 2.0 with a replacement method that
leverages a `Supplier<ClientHttpRequestFactory>` instead.

As HibernateJpaConfiguration is package private, it is no longer
possible to extend the default Spring Boot configuration to apply
advanced settings. The most notable use case for this is the
customization of Hibernate properties using instance value vs. string
value that can be set using the "spring.jpa.properties" namespace.
This commit adds a HibernatePropertiesCustomizer callback interface that
can be implemented to tune Hibernate properties at will.
Closes gh-11211
