Fix serialization warnings by applying @SuppressWarnings("serial")
when appropriate.
In certain cases and for unknown reasons, a correctly-placed
@SuppressWarnings("serial") annotation will fix the warning at the
javac level (i.e. the Gradle command-line), but will produce an
"unnecessary @SuppressWarnings" warning within Eclipse. In these
cases, a private static final serialVersionUID field has been added
with the default value of 1L.
Class#getDeclaredMembers returns arbitrary results under JDK7. This
results in non-deterministic execution of JUnit test methods, often
revealing unintended dependencies between methods that rely on a
specific order to succeed.
JUnit 4.11 contains support for predictable test ordering [1], but at
the time of this commit, JUnit 4.11 has not yet been released.
Therefore we are testing against a snapshot version [2], which has been
uploaded to repo.springsource.org [3] for easy access. Note that this
artifact may be removed when JUnit 4.11 goes GA.
- Care has been taken to ensure that spring-test's compile-time
dependency on JUnit remains at 4.10. This means that the spring-test
pom.xml will continue to have an optional <dependency> on JUnit
4.10, instead of the 4.11 snapshot.
- For reasons not fully understood, the upgrade to the 4.11 snapshot
of junit-dep caused NoSuchMethodErrors around certain Hamcrest
types, particularly CoreMatchers and Matchers. import statements
have been updated accordingly throughout affected test cases.
- Runtime errors also occurred around uses of JUnit @Rule and
ExpectedException. These have been reverted to use simpler
mechanisms like @Test(expected) in the meantime.
- Some test methods with order-based dependencies on one another have
been renamed in order to fall in line with JUnit 4.11's new method
ordering (as opposed to actually fixing the inter-test
dependencies). In other areas, the fix was as simple as adding a
tearDown method and cleaning up state.
- For no apparent reason, the timeout in AspectJAutoProxyCreatorTests'
testAspectsAndAdvisorNotAppliedToPrototypeIsFastEnough method begins
to be exceeded. Prior to this commit the timeout value was 3000 ms;
on the CI server under Linux/JDK6 and JDK7, the test begins taking
anywhere from 3500-5500 ms with this commit. It is presumed that
this is an incidental artifact of the upgrade to JUnit 4.11. In any
case, there are no changes to src/main in this commit, so this
should not actually represent a performance risk for Spring
Framework users. The timeout has been increased to 6000 ms to
accommodate this situation.

Issue: SPR-9783
Update the ReflectiveAspectJAdvisorFactory class to sort candidate
AOP methods based on their annotation first and method name second.
Prior to this the order of aspects created from annotated methods
could differ depending on the underling JVM, as first noticed under
JDK7 in SPR-9729.
- ConvertingComparator and InstanceComparator have been introduced in
support of this change, per SPR-9730.
- A shared static INSTANCE field has been added to ComparableComparator
to avoid unnecessary instantiation costs within ConvertingComparator
as well as to prevent generics warnings during certain caller
scenarios.

This renaming more intuitively expresses the relationship between
subprojects and the JAR artifacts they produce.
Tracking history across these renames is possible, but it requires
use of the --follow flag to `git log`, for example
$ git log spring-aop/src/main/java/org/springframework/aop/Advisor.java
will show history up until the renaming event, where
$ git log --follow spring-aop/src/main/java/org/springframework/aop/Advisor.java
will show history for all changes to the file, before and after the
renaming.
