Initially, these tests made sure that an old AJC bug causing
incompatibility to ECJ when using `-proceedOnError` was fixed and there
were no regressions. See also:
Now with the Java 22 changes for JEP 463 "Implicitly Declared Classes
and Instance Main Methods (Second Preview)" in JDT Core, source code is
parsed into a significantly different AST structure than before, even
when using compiler targets < 22. See also https://openjdk.org/jeps/463.
One test has been temporarily adjusted to the byte code created by
ECJ/AJC now.

If any of the old Ant builds, e.g. tests/profiling/build.xml, which
have never been mavenised, need JDT Core, they should be converted to
Maven builds and refer to it as a regular dependency. As is, the Ant

Remove Apache Commons from 'lib' module, update remaining dependencies
Of beanutils, collections, digester and logging actually only digester
and logging are directly used in AspectJ code. Therefore, remove the
unused ones and upgrade the remaining libraries' versions to ones which
also have source JARs on Maven Central. This makes downloading sources
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.

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

was previously commented out, has been activated and passes, see #141.

Fix: AllTestsAspectJ171 runs correct NewFeatures suite

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

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 I am still unsure, if we need these tests at all. Obviously, they

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.

Remove WeavingAdaptor.couldWeave()
WeavingAdaptor.couldWeave() tested two things: whether this specific
class (by its name) should be excluded from weaving, and whether the
class has generated classes associated with it (in which case we avoid
weaving to avoid re-creating those generated classes). However, if the
class has generated classes associated, couldWeave() is not called at
all because of the new wovenWithGeneratedClass() test, so we have
only the name test which is now called directly.

Use previous weaving result if classes were generated during weaving
A parallel-capable class loader might load the same class multiple times
in multiple threads, see
https://docs.oracle.com/javase/7/docs/technotes/guides/lang/cl-mt.html.
In this scenario, the JVM instrumentation mechanism invokes the AspectJ
weaver twice on the same class. In simple weaving scenarios, this would
just cause weaving logic to run multiple times and produce the same
result for each thread, but if the weaver is generating new classes,
it is undesirable to generate those classes multiple times.
To avoid this, the generatedClasses map in WeavingAdaptor keeps track of
classes for which inner classes were generated and avoids re-weaving
them. However, before this change, if a class was found in the generated
map, the weaver would return the un-woven bytes, which would cause
AspectJ not to work for some of the threads.
This change returns the woven bytes instead of re-running weaving.

Overhaul ClassLoaderWeavingAdaptor to use statically initialised Unsafe
instances and method handles pointing to their 'defineClass' methods.
Those now work universally on JDKs 8-21. In older JDKs, the method used
to be in sun.misc.Unsafe, in more recent ones on jdk.internal.misc.Unsafe.
It is challenging to fetch instances, especially as reflection
protection and module boundaries have been increased in the JDK
progressively. But finally, a solution was adapted from Byte Buddy (BB).
Kudos to BB author Rafael Winterhalter. The previous solution to use
ClassLoader::defineClass and require '--add-opens' is no longer
necessary for the first time since it became necessary in AspectJ 1.9.7
with Java 16 support.
Add org.ow2.asm:asm-common as a dependency everywhere org.ow2.asm:asm
was used before. Maybe that is too many places, but no worse than before.
