Prior to this commit, custom `ProtocolResolvers` set on the
`ApplicationContext` were lost when Devtools is used as the customized
`ResourceLoader` did not copy any customization made to the default
resource loader.
This commit makes sure to copy any `ProtocolResolver` set on the context.

Previously, reflection was used to set the OBJENESIS field of
DummyInvocationUtils with an Objenesis instance that does not use
caching. This has stopped working as the field is now declared final.
This commit updates the approach take by HateoasObjenesisCacheDisabler
to disable Objenesis's cache. Rather than changing the value of the
OBJENESIS field on DummyInvocationUtils, the cache field on the
ObjenesisStd instance is set to null instead. This has the desired
effect of disabling Objenesis's caching.

Previously, when DevTools' was used it would set the application
context's ResourceLoader and overwrite any custom ResourceLoader that
had been configured. On the rare occasion when the user had customized
the ResourceLoader this meant that the customization was lost and
certain resources would become unavailable.
This commit updates DevTools' ResourceLoader to delegate a custom
ResourceLoader if one has been configured. If one has not been
configured it delegates as before, i.e. to
WebApplicationContextResourceLoader for web applications and to
DefaultResourceLoader for all others apps.

The intent of the test is to:
1. Make a change
2. Sleep for long enough for that change to be picked up
3. Make another change
4. Stop that watcher after 1 further scan has been performed
5. Assert that a further scan was performed by checking that two
separate sets of changes (step 1 and step 3) have been picked up
Previously, step 2 relied on simply sleeping for a period of time
longer than the polling interval. In reality, the polling interval
is only a minimum time between scans and the actual time between them
depends on thread scheduling, GC pauses, etc. This lead to the
test failing intermittently if the scan didn't happen in a timely
manner.
This commit removes the sleep and replaces it with a while loop that
waits for first change to be picked up. This ensures that the second
change will be detected separately from the first and that two
separate change sets should always be available once the watcher has
stopped.

Update ClassLoaderFilesResourcePatternResolver to support servlet
resources when it's being used with a WebApplicationContext.
Prior to commit 918e122ddc a `ResourceLoader` was not added to the
`ApplicationContext`, meaning that servlet resources could be found by
virtue of the protected `getResourceByPath()` method. Following commit
918e122ddc, the context `ResourceLoader` is set, meaning that all calls
to `getResource` delegate to the `ResourceLoader` and the
`ApplicationContext` methods are not invoked. Since the devtools
`ResourceLoader` wasn't Servlet aware, servlet resources could not
be found.
Fixes gh-7752
We use some internal Mockito classes and some breaking API changes
have been made to them in Mockito 2. This commit introduces a utility
class, SpringBootMockUtil, to shield our code from these differences.
Mockito 1 is called directly and Mockito 2 is called via reflection.
To allow these changes to be tested, FilteredClassPathRunner has been
enhanced to also support overriding a dependency on the class path.
As a result it has been renamed to ModifiedClassPathRunner. The new
ClassPathOverrides annotation can be used to provide the Maven
coordinates of one or more dependencies that should be resolved and
added to the class path. Such additions are added to the start of
the class path so that they override any existing dependency that
contains the same classes.

Update `DevToolsPropertyDefaultsPostProcessor` so that property defaults
are only added at development time. Properties are now added only when
`Restarter` is initialize or remote devtools is enabled.
Fixes gh-7014
This commit switches off the auto-configured JspServlet's
development mode by default. Development mode is then switched on
when DevTools is on the class path.
Closes gh-7039
Prior to this commit any application configured to write
`META-INF/build-info.properties` could trigger unexpected application
restarts. The problem is particularly prevalent when using Eclipse M2E in
combination with Maven's `spring-boot-maven-plugin` `build-info` goal
and Gradle's `springBoot` `buildInfo()`.
Closes gh-7002
DevTools deliberately throws an uncaught exception on the main thread
as a safe way of causing it to stop processing. This exception is
caught and swallowed by an uncaught exception handler. Unfortunately,
this has the unwanted side-effect of causing the JVM to exit with 1
once all running threads are daemons.
Normally, this isn't a problem. Non-daemon threads, such as those
started by an embedded servlet container, will keep the JVM alive and
restarts of the application context will occur when the user makes to
their application. However, if the user adds DevTools to an
application that doesn't start any non-daemon threads, i.e. it starts,
runs, and then exits, it will exit with 1. This causes both
bootRun in Gradle and spring-boot:run in Maven to report that the
build has failed. While there's no benefit to using DevTools with an
application that behaves in this way, the side-effect of causing the
JVM to exit with 1 is unwanted.
This commit address the problem by updating the uncaught exception
handler to call System.exit(0) if the JVM is going to exit as a
result of the uncaught exception causing the main thread to die. In
other words, if the main thread was the only non-daemon thread, its
death as a result of the uncaught exception will now cause the JVM
to exit with 1 rather than 0. If there are other non-daemon threads
that will keep the JVM alive, the behaviour is unchanged.

Previously, Spring Data Redis assumed that the class loader that loaded
its classes would also be able to load the application’s classes. This
assumption is faulty when there are multiple class loaders involved
such as when using dev tools or when Spring Data Redis is installed as
a shared library in a servlet container.
DATAREDIS-427 and DATAREDIS-501 removed this assumption by making the
default serialiser use the bean class loader. DevTools configures this
class loader to be the restart class loader which can load the
application’s classes. As a result of moving to Hopper SR2 snapshots,
these fixes are now available and we can remove our custom serialised.
Closes gh-5760
