Known limitations:
* Spring's SingleConnectionFactory and CachingConnectionFactory do not support createContext calls for JMSContext creation at this point. Note that the JMSContext model bypasses the point of a Connection/Session pool anyway; this will only really work with a native JMS 2.0 ConnectionFactory and provider-specific pooling such as in an EE environment.
* JmsTemplate has no out-of-the-box support for send calls with an async completion listener. Note that a CompletionListener can be specified in a custom ProducerCallback implementation if really necessary.
There is no special support for the simplified JMSContext API, and likely never will be: JMSContext can be used from a native ConnectionFactory directly. @Inject JMSContext isn't supported due to rather involved rules for defining and scoping the injected context which are quite at odds with the Spring way of doing these things. We strongly recommend JmsTemplate instead, or @Resource ConnectionFactory with a createContext call within a Java 7 try-with-resources clause (as shown in the specification). After all, JMSContext has primarily been designed with EE's one-session-per-connection model and JTA transactions in mind, not with Spring-style use of a native JMS provider and native JMS transactions.

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.
In particular, avoiding synchronized Sets and Maps wherever possible (preferring a ConcurrentHashMap even instead of a synchronized Set) and specifying appropriate ConcurrentHashMap initial capacities (even if we end up choosing 16).
Before this change there were numerous javadoc warnings being reported
while building Spring framework API.
This commit resolves most of the javadoc warnings, reducing the total
number from 265 to 103.

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.
