Add decade 2020-2029 to copyright years in Checklics
FWIW, I just wanted to know if the tests in module 'build' would still
pass. They did not find copyrights for more recent years, so I added
them here.
But I am still unsure, if we need these tests at all. Obviously, they
were not running during CI builds, i.e. they seem to be non-essential.
But chances are, they were forgotten to be added to the suite.
BTW, running the tests in module 'build' with '-Drun.build.tests=true'
is failing, too, because some old JDK classes looked up there no longer
exist in more recent JDKs.

Avoid "Last updated [timestamp]" footer on each docs page
Set Asciidoctor option 'nofooter' to avoid the annoying timestamps. It
makes updating the website difficult, because always there are "changes"
in each file. Diffing real changes in generated files for the website
before committing becomes difficult. Furthermore, the user does not have
any immediate benefit for most documents, as they change infrequently or
never (e.g. old release notes).

Globally replace "http:" by "https:" in non-XML files
Maybe, the XML files and Maven wrapper files will follow. First, let us
find out if this breaks the build, maybe some tests are asserting on
"http:". But there, the replacement would also have taken place, so
probably it just works.

Classes and methods named '_' are no longer allowed in ECJ, obviously
also not for old target versions like 1.5. This probably is due to
the added support for unnamed patterns and classes in the latest
upstream JDT Core merge. Therefore, we simply rename '_' to '__'.

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.
Relates to #279.
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.
Relates to #279.
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.
Fixes #279.
Change value of woven class in generatedClasses map
Store the woven class and not a generated (inner) class as value of the
woven class name. This has no effect in this commit, because the value
is not consulted at all, but will be used later on.
Relates to #279.

Weaver returns null instead of original bytes for unwoven classes
This change makes sense independently of #277, but also enables using
- cp "my.jar;aspectjweaver.jar"
-XX:+AllowArchivingWithJavaAgent
-javaagent:aspectjweaver.jar
while creating a CDS archive. Afterward, the application can be run in
its woven state from the CDS archive even without '-javaagent', because
the byte code was archived in its woven state ("poor man's AJC"). See
https://github.com/eclipse-aspectj/aspectj/issues/277#issuecomment-1931142753
for details.
Fixes #277.

On my workstation, more recent JDKs generate partly German javadocs.
Background: Avoid non-English javadoc generation. Due to
https://bugs.openjdk.org/browse/JDK-8222793 reoccurring at least in JDKs
19-21 and also being broken in some older JDKs, we cannot rely on just
setting the locale parameter, but also need the 'user.language' and
'user.country' parameters in 'additionalJOptions' as a workaround.

Always use ":leveloffset: +1" with ":doctype: book"
Headlines per ADOC file should start at level 1, not 2. Adjusting the
level offset for books helps to avoid warnings when including book

Remove some old files relating to AspectJ Debugger ajdb
If ajdb ever existed and was part of the product, it must have been 20+
years ago. There are still some references to it in old release notes

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.
Add missing dependency on loadtime to aspectjweaver. This kept a build
like "mvn install -am -pl aspectjweaver" from picking up changed
loadtime classes.

- Redundant copies of HTML files used in AspectJ installer, which
already exist as resource files in module 'build'
- Null-sized AspectJ library JARs which probably were used to trigger
certain build steps in the former Ant build
- BridgeVersion.java.txt, which has been replaced by a regular
org.aspectj.bridge.Version class which can dynamically determine
versions from a properties file instead of relying on them being
hard-coded into the template.

The former HTML file was moved up one directory level and converted to
asciidoc format. Therefore, include the ADOC file from the correct
location now.
Alternatively, we could have included the generated HTML from the
aj-build/dist/docs/doc directory, but that would have meant adding a
dependency to the 'docs' module to several other modules for this one
file. Actually, asciidoc has become a widely used and accepted format
for documentation and is human-readable by design. Therefore, it is OK
to include the ADOC file. The important thing is that the licence
information
- is contained in each published artifact,
- can be found easily,
- its content is human-readable.
All these requirements are still met with this change. Arguably, ADOC is
easier to read than HTML and does not even need a web browser.
