Comment on newly pointcut parsing found problem in test class
A pointcut like
execution(*..Collection<?>[] *(..))
leads to an AJ core dump, which is something I noticed while fixing a
test in the previous commit. I am going to create a new issue for it and
link to this commit later.

After the changes, the weaver's behaviour is now slightly different, but
not actually buggy. Actually, in one case there is now a weaver warning
for a non-matching pointcut which should have been there before, but was
not. I.e., things have improved and the tests are even a bit better now.

WildTypePattern: fix hashCode and toString methods
Especially 'hashCode' did not correspond to 'equals', disregarding
several fields, array dimension information being only one of them. This
led to parts of pointcuts being ignored, because they were regarded as
duplicates. Example:
execution(Foo* *(..)) && !execution(Foo*[] *(..))
Here, the negated pattern was falsely regarded as equal to the first
pattern, leading to an "A && !A" situation, i.e. no match at all.
Furthermore, 'toString' did not print array strings, i.e. instead of
"Foo*[][]" something like "Foo*" was printed. This false information was
also present in annotations generated by the weaver.
FuzzilyMatchingAspect was adjusted to actually match exactly once, as
expected, for the "Foo*" return types, i.e. exclusions for the array
return types have been added.
Relates to #24.

Refactor, comment and reactivate Ajc183Tests.testAnnoStyleDecp_442425
This test was always inactive and did not add any value other than
during development. No it runs, passes and documents the status quo of
- what was fixed (regression for AJC 1.8.2 core dump fixed in 1.8.3),
- the current limitations of @DeclareParents and @DeclareMixin
regarding generic interfaces.

BcelTypeMunger.mungeMethodDelegate: only use 'synchronized' when necessary
Relates to #198. Now, we create a delegate method body which basically
looks as follows:
public void methodOne() {
if (this.ajc$instance$MyAspect$MyMixin == null) {
synchronized(this) {
if (this.ajc$instance$MyAspect$MyMixin == null) {
this.ajc$instance$MyAspect$MyMixin = MyAspect.aspectOf().createImplementation(this);
}
}
}
this.ajc$instance$MyAspect$MyMixin.methodOne();
}

Fix #366085 concerning declared annotations with source retention
See https://bugs.eclipse.org/bugs/show_bug.cgi?id=366085.
See https://stackoverflow.com/q/74618269/1082681.
The issue described in the Bugzilla issue is about 'declare @type', but
similar issues also existed for 'declare @field', 'declare @method',
'declare @constructor'. This fix is rather superficial and leaves
things to be desired, because it is rather hacky and simply ignores
errors source retention annotation declarations during weaving. A better
fix would drop the corresponding declarations while parsing and also
issue compiler warnings in each case.

OutputSpec.matchesThisVm better supports version ranges
vmVersionRanges might be a single version like "9", a list of versions
like "1.2,1.3,1.4,1.5", an equivalent range of "1.2-1.5", an open range
like "-1.8", "9-" (equivalent to "9+") or a more complex list of ranges
like "-1.6,9-11,13-14,17-" or "8,11,16+".
Empty ranges like in "", " ", "8,,14", ",5", "6-," will be ignored.
I.e., they will not yield a positive match.
Bogus ranges like "9-11-14" will be ignored, too.
Existing XML test specs using '<line text="..." vm="v,v2,...,vn"/>
have been adjusted to use version ranges rather than long lists of
consecutive versions. Furthermore, ranges with a trailing '+' like '14+'
were replaced by using the new canonical format '14-', even though the
parser still correctly recognises '14+'.

For now, only the "pattern matching for switch" tests from previews 1
and 2 were adjusted to work in preview 3, because guarded patterns were
replaced by 'when' clauses in 'switch' blocks. Therefore, existing test
classes did not compile anymore and had to be replaced by syntactically
upgraded versions with content merged from preview 1 and 2 classes.

Firstly, Batik is not needed for running AspectJ tests.
Secondly, the fixed Windows path separators led to GitHub CI/CD tests
failing under Java 18+ on GitHub. Replacing ';' by 'File.pathSeparator'
would have fixed the problem, but removing the paths altogether is the
cleaner solution.

This fixes a partial path traversal vulnerability.
Replaces `dir.getCanonicalPath().startsWith(parent.getCanonicalPath())`, which is vulnerable to partial path traversal attacks, with the more secure `dir.getCanonicalFile().toPath().startsWith(parent.getCanonicalFile().toPath())`.
To demonstrate this vulnerability, consider `"/usr/outnot".startsWith("/usr/out")`.
The check is bypassed although `/outnot` is not under the `/out` directory.
It's important to understand that the terminating slash may be removed when using various `String` representations of the `File` object.
For example, on Linux, `println(new File("/var"))` will print `/var`, but `println(new File("/var", "/")` will print `/var/`;
however, `println(new File("/var", "/").getCanonicalPath())` will print `/var`.

Make IStateListener.aboutToCompareClasspaths use typed lists
Before, the signature was:
void aboutToCompareClasspaths(
List oldClasspath, List newClasspath);
Now it is:
void aboutToCompareClasspaths(
List<String> oldClasspath, List<String> newClasspath);
AJDT will also use the typed version after generics refactoring.

POM bug: separate jvm.arg.allowSecurityManager from jvm.arg.addOpens
Before, this was in a single variable, and for JDK 18+, the security
manager setting also falsely overwrote the '--add-opens' command. This
was the root cause for a few dozen LTW tests to fail on JDK 18, if they
were not run in full LTW mode, i.e. in a separate JVM.
After this fix, it should be possible to revert the corresponding
commits, at least their non-cosmetic parts.

Name annotation vs native style aspects uniformly in github_128 tests
Trying to find the difference between byte code generated by AJC for
functionally identical annotation vs native style aspect, I move the
aspects into subdirectories in order to be able to name them
identically. This way, when decompiling them with javap or Fernflower it
is easier to diff them later.
Why the decompilation? Because for the thread pool testing scenario
native syntax passes while annotation syntax fails. I.e., we need to
find the difference. That can be done by reading source code, if you
know where to look, or by starting with reverse engineering in order to
first understand more and look at the code later.

Expand "asynchronous proceed for nested around-advice" to 4 scenarios:
1. @AspectJ syntax, threads created inside advice code
2. @AspectJ syntax, submit runnable to thread pool
3. native syntax, threads created inside advice code
4. native syntax, submit runnable to thread pool
Scenarios 1, 3 and 4 are passing, while 2 is failing.
