Make BCEL classpath utility recognise Java 16-19, fixing many tests
This is a follow-up commit on @07af5d41:
Inside org.aspectj.apache.bcel.util.ClassPath.getClassPath(), some JVM
version matching occurs which previously did not include Java 16 (I also
added 17-19 to the regex matcher). This fixes test errors like:
java.lang.ClassCastException:
class org.aspectj.weaver.MissingResolvedTypeWithKnownSignature
cannot be cast to class
org.aspectj.weaver.ReferenceType
(org.aspectj.weaver.MissingResolvedTypeWithKnownSignature and
org.aspectj.weaver.ReferenceType are in unnamed module
of loader 'app')

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.

Make BCEL classpath utility recognise Java 15, fixing many tests
Inside org.aspectj.apache.bcel.util.ClassPath.getClassPath(), some JVM
version matching occurs which previously did not include Java 15.
Technically, AspectJ 1.9.6 does not support Java 15, but on GitHub
Actions there is a build job running on a JVM 15. This change should at
least make the weaver tests pass, making that test job more meaningful.
This fixes test errors like
java.lang.ClassCastException:
class org.aspectj.weaver.MissingResolvedTypeWithKnownSignature
cannot be cast to class
org.aspectj.weaver.ReferenceType
(org.aspectj.weaver.MissingResolvedTypeWithKnownSignature and

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 common usage patterns of java.util.Map that could be replaced with Java 8 methods: getOrDefault(), computeIfAbsent(), putIfAbsent(), merge(), or replaceAll().

Collections.sort() can be replaced with List.sort()
Reports calls to Collections.sort(list, comparator) which could be replaced with list.sort(comparator).

Reports the copying of array contents to a collection where each element is added individually using a for loop. Such constructs may be replaced by a call to Collection.addAll(Arrays.asList()) or Collections.addAll().

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