Methods Integer.parseInt/Boolean.parseBoolean should be preferred over Integer.valueOf/Boolean.valueOf/ if final result is primitive.
They are generally faster and generate less garbage.
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.

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.

Add Java 16 test suite for AspectJ 1.9.7 + test refactorings
- Test all features which were preview in 14+15 and are now final in 16,
compiling them with language level 16.
- For Java 15 we only have sanity tests (and of course the Java <14
tests), compiling Java 16 features to target 15 does not seem to work.
- Test remaining Java 16 preview feature (sealed classes).
- Instead of overriding runTest(String) in several base classes like
XMLBasedAjcTestCaseForJava*Only or XMLBasedAjcTestCaseForJava*OrLater,
we now override setUp() from JUnit's TestCase base class. This will
run before runTest(String) and make the tests fail much faster, if a
user tries to run them on the wrong VM.

This made ModuleTests.testBuildModuleAndApplyAspectsFromAspectPath fail
because a file delete job for a module JAR failed after a previous
compile job had called FileUtil.isZipFile(File) in which the opened zip
file was never closed. A try with resources fixes that.
Maybe the corresponding test worked on Linux before, I did not try. I
just know that Linux is more forgiving about deleting open files while
on Windows they are being locked, which makes Windows the better system
to search for open file leaks.

Reports on declarations of Collection variables made by using the collection class as the type, rather than an appropriate interface.

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.

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.

Reports "unboxing", e.g. explicit unwrapping of wrapped primitive values. Unboxing is unnecessary under Java 5 and newer, and can be safely removed.

Reports for loops which iterate over collections or arrays, and can be replaced with an enhanced for loop (i.e. the foreach iteration syntax).
