- Improvement: Also add CompilationAndWeavingContext for constructor
with causing exception
- Remove home-brew stack trace printing, just call super constructors
Signed-off-by: Alexander Kriegisch <Alexander@Kriegisch.name>
- Bugfix: Flush stream.
- Adjust format to more closely resemble JVM format. E.g., do not print
the causing exception name twice.
- Add TODO, because this whole custom stack trace printing can just go
away. The JVM format should do just fine. This commit is merely meant
to document the decision to remove the cruft in the next commit.

New Xlint warning 'arrayCannotBeVoid' when resolving 'void[]'
Because void arrays are illegal (and nonsensical), now there is a new
Xlint warning whenever World.resolve resolves a new 'void[]'. Because
in the World class we do not have any source context, no path + line
number are logged. The user only sees something like:
[warning] arrays cannot have a void type, but found 'void[]' in
pointcut [Xlint:arrayCannotBeVoid]
Then later, if due to the returned MissingResolvedTypeWithKnownSignature
type a joinpoint does not match, there is an additional
my/path/MyAspect.aj:42 [warning] advice defined in MyAspect has not
been applied [Xlint:adviceDidNotMatch]
log line, but not necessarily anywhere near the former one.
On the one hand, this is better than nothing. OTOH, comparing the
situation with no logging message other than Xlint:adviceDidNotMatch in
case of something equally illegal like 'Foo<int>' (primitive generic
type parameter), this is actually more than we have in several other
situations and might even be regarded as superfluous. In case of
multiple 'void[]' cases within a big number of aspects, the same aspect
or even the same pointcut, the user would have no clue where exactly to
search for it. He would just see multiple log messages without source
context.
One option would be to set 'arrayCannotBeVoid=ignore' in
XlintDefault.properties, so the user would have to explicitly activate
it. But IMO, this message should be visible by default.
Another option would be to find out how to defer logging the messages
until later similarly to BcelWeaver.warnOnUnmatchedAdvice and then to
bulk-print them. But in order to achieve that, the information about the
existence of any 'void[]' occurrences would have to be stored in a flag
similar to BcelAdvice.hasMatchedAtLeastOnce, bloating BcelAdvice for
that rare case. Alternatively, each advice pointcut could be
heuristically scanned for the literal substring 'void[]', logging the
Xlint message if it is found anywhere.

UnresolvedType.signatureToName: fix '*' case for generic type '?'
In generic type lists, after a '*' in any type parameter list, sometimes
the '*' (which should be converted to '?') itself and always the
subsequent parameters would be missing from the signature:
- '[Pjava/util/Collection<*>;' yielded
'java.util.Collection<>[]', but should be
'java.util.Collection<?>[]'
- '[Pjava/util/Map<*Pjava/util/List<[Ljava/lang/Integer;>;>;' yielded
'java.util.Map<?>[]', but should be
'java.util.Map<?,java.util.List<java.lang.Integer[]>>[]'
This is now fixed.

WildTypePattern: match generic type params correctly for array types

WildTypePattern.toString: do not parenthesesise generic type list
It is unnecessary to represent a pattern list 'A,B,C' as '(A,B,C)'. Not
only does it look ugly in a type signature like 'org.acme.Foo<(A,B,C)>',
but also is it not valid Java syntax. While the latter might not be
strictly necessary in a String representation, it certainly is
desirable, if such representations are ever used to generate code or
@AspectJ pointcut annotations.

SignaturePattern: Add exception for meta annotations
Upon meta annotation usage in signature patterns, lint warnings like the
following were issued during type parameter traversal:
does not match because annotation @java.lang.annotation.Inherited
has @Target{ElementType.ANNOTATION_TYPE} [Xlint:unmatchedTargetKind]
To avoid this, we now heuristically check if we are in a meta annotation
situation and, if so, permit it.

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.

LangUtil: remove methods like 'is11VMOrGreater', 'is1dot5VMOrGreater'

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.

NotTypePattern: Fix matching problem for negated type patterns
The implementation for boolean matchesArray(UnresolvedType type) was
buggy.
'!String' should match anything but String, no matter if it is
an array or not, e.g. int, void, int[], String[], String[][].
'!String[]' should match anything but String[], no matter if it is
an array or not, e.g. int, void, int[], String, String[][].

Add method ArrayReferenceType.equals to fix failing tests
This also fixes a bug. Previously, ResolvedType.equals was used for
equality check, and in there is a '==' comparison, which does not work
for two different ArrayReferenceType instances, even if the component
type is the same.

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'.

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.

This fixes:
- negating annotation style if() pointcuts doesn't work
- annotation style if() pointcut not able to use a binding

Fixes #120,#122
Methods Integer.parseInt/Boolean.parseBoolean should be preferred over Integer.valueOf/Boolean.valueOf/ if final result is primitive.
They are generally faster and generate less garbage.
Trailing whitespaces are useless. Most of code-styles forbids them. Most of editors always trim them on save.
I propose to clean up project from trailing whitespaces in all java files at once.
Strip down compiler messages to AspectJ-specific ones
Delete all properties from messages_aspectj.properties which were just
copied from Eclipse and basically the same. This not only gets rid of
duplicates but also eliminates differences found between upstream and
AspectJ strings which were just cause by errors or oversights during
manual upgrade.
TODO:
- Find a way to print the '-X' options as info instead of yielding
'abort', making it seem as if compilation failed and print the usage
message to stdErr instead of stdOut.
- Eclipse also has misc.usage.warn, not just misc.usage, i.e. usage
info specifically for warning options. Make sure that AspectJ uses
it consistently.
- Find a way to merge AspectJ-specific options into the standard
Eclipse usage text instead of completely replacing it, further
reducing the need to merge and copy upstream content.
