Bugfix: caret error marks in compiler output too short
This very old bug in EclipseAdapterUtils calculated the '^' caret error
marks incorrectly. The marks were too short like this:
void m() { return vax[3]; }
^^^^^^^^^^^
Where the correct result would look like this:
void m() { return vax[3]; }
^^^^^^^^^^^^^^
This was due to the rather complicated way in which first surrounding
context code - here the leading 'void m() { ' and trailing ' }' - was
first added and then possible leading white space was cut off again from
the left. It is difficult to explain, the code is a nightmare, trying to
work with char arrays, counting indexes, repeatedly using
System.arraycopy and using lots of counters and offsets. I would have
liked to simplify the code, converting char[] buffers to Strings, but
decided to keep the basic structure for now, not sure what kind of
memory or performance considerations led to this design.

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.

Fix PointcutRewriterTest, add LogicalPointcutStructure test helper class
After WildTypePattern.hashCode was fixed in the previous commit,
PointcutRewriterTest started failing, because in many places it was
falsely relying on a specific order of hash codes, which cannot be
guaranteed, especially since more instance fields are part of the hash
code now in accordance with 'equals'.
The new test helper class LogicalPointcutStructure is able to recognise
chained '&&' and '||' pointcuts of the same logical nesting level,
un-nesting them from the actual pointcut structure and making them
comparable, disregarding their order. I.e., something like
((A && B) && C) && D
is actually recognised to logically be
A && B && C && D
and equivalent to e.g. either of
D && B && A && C
A && B && D && C
C && A && D && B
This helps to compare rewritten pointcuts, as long as their logical
structure has not been altered.
Relates to #24.

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.

Handle one- and multi-dimensional array return types correctly
Fixes https://github.com/eclipse/org.aspectj/issues/24, both the array
return type matching as such as well as matching dimensionality patterns
correctly. E.g., 'Foo*[]' is not the same as 'Foo*[][]'. This also works
correctly in combination with asterisks, even for primitive types, i.e.
'in*[][]' correctly matches a 2-dimensional array of 'int'.

Instead of importing com.sun.org.apache.bcel.internal.Const, use

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`.

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.
