Due to the latest improvements, an error which was previously not thrown
unexpectedly according to a source code comment in test aspect
ParameterizedTypesInAnnotationPatterns.aj is now thrown for this kind
of pointcut:
Fixes #211. Previously, '?' was not converted to '*' in
UnresolvedType.nameToSignature, but kept as-is. That is why - falsely -
it was necessary to handle the '?' case in UnresolvedType.forSignature
at all, reading this kind of bogus signature and creating a type for it
in TypeFactory.createTypeFromSignature. This, ironically, led to correct
JVM generic type signatures containing '*' not being handled at all.
The conversion should now work correctly both ways.

JoinPointImpl: Remove thread-locals after usage, where possible
Avoid potential ThreadLocalMap.Entry accumulation. Entry is a
WeakReference. When JoinPointImpl objects are collected by GC, Entry
instances are still be referenced by ThreadLocalMap, which leads to
memory pressure and potentially more full GCs. So, we proactively remove
ThreadLocal<Integer> arcIndex instances when arcIndex has been
decremented back to -1 per thread. This is not perfect, because not each
thread can be expected to proceed, but it should ameliorate the
situation to some degree.
Fixes #302.

Revert WeavingAdaptor generated class map optimisation
This was introduced in commit 8a4aa03845 of PR #278 contribution as part
of the #279 fix. The contributor thought that the generated closure
class entries were never used, but in fact AJDT class OSGiWeavingAdaptor
relies on the presence of those entries.
To the best of my present knowledge, it looks as if this change was the
root cause of https://github.com/eclipse-aspectj/ajdt/issues/57.
Therefore, I reverted it, simultaneously refactoring Iterator::remove
usage to delete entries from the map to Collection::removeIf.

Remove Apache Commons from 'lib' module, update remaining dependencies
Of beanutils, collections, digester and logging actually only digester

from GitHub and packaging separate commons.jar and commons-src.zip

Throw exception for minimal AJC runtime version violation
When running AJC, throw an AbortException(MINIMAL_JRE_VERSION) instead
of just logging an error, if the minimal JRE version requirement is
violated. Otherwise, in-process compilation would not fail due to the
skipped System.exit(-1) that was used before. In-process compilation is,
for example, relevant for AspectJ Maven Plugin, but also for non-forked
executions of Plexus AspectJ via Maven Compiler.
I am not 100% sure that AbortException is the appropriate exception
type, because it was designed for an aborted compilation process and
here compilation has not even started yet, but it seems to work fine.

according to https://rules.sonarsource.com/java/tag/leak/RSPEC-5164/.
Now, there no longer is a thread-local stack of AroundClosure instances,
but rather a list of them, which can only grow but never shrink.
Instead, we now have a thread-local (integer) list index, for every
thread being initialised with pointing to the last element. I.e., every
thread can unwind by decrementing the index while proceeding,
independently of other threads.
A positive side effect is that this approach also works for long-lived
threads from thread pools, used by executor services. Hence, test
Bugs199Tests.testAsyncProceedNestedAroundAdviceThreadPool_gh128, which
was previously commented out, has been activated and passes, see #141.
I am not sure if this brings @AspectJ style, non-inlined, nested around

Fix: AllTestsAspectJ171 runs correct NewFeatures suite
While fixing #285, I noticed that *.ajc171.NewFeatures was never
executed as part of the AspectJ test suite, because since 2012 falsely
*.ajc1610.NewFeatures was imported and executed a second time instead.
In addition to an outdated AspetJ weaver library in 'lib', this was one
more factor why the regression bug was never spotted.

New abstract class JavaVersionSpecificXMLBasedAjcTestCase
Replaces now obsolete base classes
- XMLBasedAjcTestCaseForJava[n]OrLater,
- XMLBasedAjcTestCaseForJava[n]Only.
The new class is parametrised with minimum and maximum Java version and
hence can replace all the other classes. This does not only apply the
DRY principle, but also makes adding tests for new Java versions less
tedious.
By chance, I also noticed missing sanity tests for Java 12, which I

SOURCE_INPUTS, TARGET_INPUTS, COMPLIANCE_INPUTS are now populated in a
'for' loop in a static initialiser block. I.e., adding support for a new
Java version is now as simple as incrementing field JAVA_VERSION_MAX. In
case ECJ raises the minimum supporter compiler source/target version,
field JAVA_VERSION_MIN needs to be incremented. But that should happen
less frequently.

for now, the most important places should be covered:
- AJC version string
- Test infrastructure (test suites, classes and XML files)
- BCEL class file version MAJOR_*, MINOR_* constants
- AjcTask constants for compiler source, target, release
- LangUtil::is*VMOrGreater methods
- ASM and JDT Core dependency versions
- CI workflow file
- Release notes

But chances are, they were forgotten to be added to the suite.

Store only weaved class names in the generatedClasses map
The generatedClasses map contained both keys of woven classes that had
generated classes associated with them, and the keys of the generated
classes themselves. It seems like this map is never consulted for the
generated class key - the generated class is generated from within the
context of woven class loading / retransformation, and thus no transform
event is generated for it by the JVM. Because of that, we do not need to
guard against re-weaving it. Other uses of generatedClasses map are for
full/empty tests, where the woven class key is sufficient. This change
simplifies deletion of a class because we do not have to look for its
associated generated classes.
