This is a bugfix release, reverting the essential parts of commit
f70aeb5e, because it causes AspectJ Maven integration tests using
javadoc to fail on JDK 8.

Before, we used 1.9.7.BUILD-SNAPSHOT, which according to Andy Clement
was originally an intent across a group of Spring projects he was
involved in, to ensure that SNAPSHOTS were sorted alphabetically ahead
of MILESTONEs and ahead of RCs.

This involves replacing references in weaver application code as well as
a few tests.
In order to make AspectJ weaver + tools contain a relocated ASM version,
I added a Maven Shade relocation step after Maven Assembly created the
uber JARs. Relocation works for both binaries and sources and also
encompasses Class::forName calls like in class AsmDetector.

Upon special request by Andy Clement, I included 'lib' as a child module
in the parent POM again, making several modules which refer to
downloaded library files dependent the 'lib' module. I am not sure I
caught all of them, but I hope so.
Now after cloning the project and configuring the token for reading from
GitHub Packages (sorry!), you can just run a Maven build for the main
project and no longer need to fail the first build, read the Maven
Enforcer message and run 'cd lib && mvn compile' as a first step. This
convenience comes at the price of a more complex POM and two new
profiles:
- Profile 'provision-libs' is auto-activated by the absence of a
marker file, kicking off the library provisioning process and
creating same marker file at the end, if successful. Therefore,
during subsequent builds libraries will not be re-provisioned,
because the marker file exists and Maven skips all download and
(un)zip steps, which saves build time and bandwidth. Otherwise
offline builds would not work either.
- Profile 'clean-libs' needs to be activated manually, because by
default 'mvn clean' will not erase provisioned libraries. In most
cases, even after a clean a developer does not want to re-provision
all libraries if they have not changed (e.g. new JDT Core build).
But if you do wish too erase the libraries and the marker file, just
call 'cd lib && mvn -P clean-libs clean'.
Please note: The Maven Enforcer build step, which additionally checks
for existence of other files, still exists and was moved from the parent
POM to 'libs'. No matter if provisioning was just done or skipped
because the main marker file exists, a quick heuristic check for that
list of files is done during each build, failing the build with a
comprehensive message if an inconsistency was found. The error message
says which files are missing and tells the user:
"There is an inconsistency in module subdirectory 'lib'. Please run
'mvn --projects lib -P clean-libs clean compile'. This should take
care of cleaning and freshly downloading all necessary libraries to
that directory, where some tests expect them to be."
This should cover the topic.

Remove redundant 'name' and 'packaging' tags from POMs
If 'name' is identical to 'artifactId' and 'packaging' has the default
value 'jar', we can just remove those tags from the POM.

Clean up Maven dependencies using 'dependency:analyze' goal
Notably, this change involves a partial revert of @4a5660b3, because we
are not using JUnit Jupiter yet but still JUnit 4 tests. See discussion
under commit at https://github.com/eclipse/org.aspectj/commit/4a5660b3.
Many other warnings - concerning both used undeclared and unused
declared dependencies - were eliminated by adding or removing the
corresponding dependencies from the POMs. Furthermore, I tried to make
sure that some clearly test-scoped dependencies are now actually
declared as such, so as to avoid unwanted transitivity bleeding into
compile scope and maybe unwanted classes ending up in uber JARs via
Maven Shade or Maven Assembly.
TODO: I am not so sure why modules other than 'run-all-unit-tests' would
depend on test JARs. I hope I broke nothing essential there. As of
today, the other modules where I found '<type>test-jar</type>'
dependencies are:
- ajde
- testing
- testing-drivers
- tests
- weaver

Replace JDT Core system dependency by deployed one
Get rid of system paths. Instead, rely on JDT Core Shadows to deploy
both binary and source JARs to GitHub Packages. The former module
directory was deleted completely. Instead, the JARs are redundantly
copied into 'libs/jdtcore-aj' in order to be found there by tests and
other Ant scripts.

Reports on declarations of Collection variables made by using the collection class as the type, rather than an appropriate interface.
Signed-off-by: Lars Grefer <eclipse@larsgrefer.de>
Reports Collection.addAll() and Map.putAll() calls after instantiation of a collection using a constructor call without arguments. Such constructs can be replaced with a single call to a parametrized constructor which simplifies code. Also for some collections the replacement might be more performant.
Signed-off-by: Lars Grefer <eclipse@larsgrefer.de>
There are two styles to convert a collection to an array: either using a pre-sized array (like c.toArray(new String[c.size()])) or using an empty array (like c.toArray(new String[0]).
In older Java versions using pre-sized array was recommended, as the reflection call which is necessary to create an array of proper size was quite slow. However since late updates of OpenJDK 6 this call was intrinsified, making the performance of the empty array version the same and sometimes even better, compared to the pre-sized version. Also passing pre-sized array is dangerous for a concurrent or synchronized collection as a data race is possible between the size and toArray call which may result in extra nulls at the end of the array, if the collection was concurrently shrunk during the operation.

Adjust how classpath entries manipulated for Java9 support
Prior to this AspectJ would discard ignore the ClasspathEntry
objects built by JDT and just work with the classpath as a string,
driving the JDT FileSystem to rebuild classpath entries again at
a later date using the string. This is more complex in Java9 because
the string representation was losing whether some entries came in
via modulepath. ClasspathEntry construction for modulepath entries
is non trivial (since the module-info must be processed).
The new version will cache some of the ClasspathEntry objects (those
built for modulepaths) and do more work on the AspectJ side building
classpath entries in general. It now passes these entries to a
different FileSystem entry point rather than the entry point that
takes a string path.
