Rename DOM AST class TypePattern to AbstractTypePattern
Since JDT Core 3.27 (Java 17), there is a name clash, because the new
class org.eclipse.jdt.core.dom.TypePattern (JEP 406) gets relocated to
org.aspectj.org.eclipse.jdt.core.dom.TypePattern during shading.
Fortunately, this made tests like AjASTTest and AjAST5Test fail with
rather nasty errors like:
java.lang.VerifyError: Bad return type (...)
Type 'org/aspectj/org/eclipse/jdt/core/dom/TypePattern' (...) is not
assignable to 'org/aspectj/org/eclipse/jdt/core/dom/Pattern' (...)
TODO: Update AJDT references to the renamed class in the following
classes after refreshing the AspectJ sources:
- ExtraPackageReferenceFinder
- ExtraTypeReferenceFinder
This also means, that for Eclipse 2021-09 (4.21) we need a new AJDT
update site, because simply deploying to the 4.19 one would probably
lead to problems in the IDE.

Update ECJ version, activate Java 17 preview features tests
After JDT Core (ECJ) was updated to the final Java 17 feature set, the
tests now pass as expected.

In ITD processing, use setter instead of assigning Scope directly
Change calls like
pre.scope.parent = newParent;
to this pattern:
// Use setter in order to also update member 'compilationUnitScope'
pre.scope.setParent(newParent);
This should fix lots of failing tests after updating JDT Core.

Remove remaining usage message duplication between ECJ and AJC
The resource key 'misc.usage' is completely gone from
.../jdt/internal/compiler/batch/messages_aspectj.properties. Instead,
JDT Core was adjusted in such a way as to patch the new resource key
'misc.usage.aspectj' into the upstream 'misc.usage' in the right place.
Now finally the properties file is as lean as I envisioned it to be,
without any loss of information and without the need of future manual
synchronisation of duplicate texts for every release.
At the same time, usage text detection in AjdtCommand::inferKind was
improved and also adjusted to the new situation.

After Ajc usage text output is filtered into its own category
IMessage.USAGE now - see commit @31b2d60b - some tests in module
'org.aspectj.ajdt.core' were failing. I fixed and also improved them a
bit.

Improve usage text, error and warning output in batch compiler
- Usage texts are now printed to stdOut, no longer stdErr.
- 'java ...Main -?' no longer prints usage text twice (once to stdOut
and then again to stdErr).
- AjdtCommand.inferKind: Usage texts are no longer mis-identified as
warnings or errors just because they contain substrings "warning" or
"error". Matching is now more precise, looking for "[warning]" and
"[error]". But in that case the method would not be called anyway
because errors and warnings are identified in other ways already. As a
fall-back, the categories IMessage.ERROR and IMessage.WARNING still
exist in the method.
- In case of compile errors, no usage message is printed anymore,
because previously the user had to scroll up a lot in order to see the
actual messages. This is also in line with ECJ. The same is true for
warnings, but it was like this in Ajc already.
- AjdtCommand.inferKind: There is a new category IMessage.USAGE
especially for AspectJ usage texts, which will be identified by string
matching and then correctly handled (i.e. printed to stdOut, not
stdErr).
- Usage text printing is no longer done in AspectJ but in the AspectJ
"shadows" fork of JDT. This helps to get rid of some now obsolete code
here.

- Use spaces instead of tabs for indentation.
- Document parameters bound in Eclipse JDT, e.g. {0} is not the compiler
name there but the system's path separator ';' or ':'. So if we want
to display the compiler name, we need {1}.
- For both normal usage and '-X' usage, compiler name + version are
printed now.

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.

Begin migration to 'aspectj' locale for compiler messages
Renamed messages.properties to messages_aspectj.properties and moved to
a path identical with the Eclipse original resource file. Therefore, it
is now just treated as a localised version of it.
The new jdtcore-for-aspectj.jar already contains logic to use the new
locale. Hence, BuildArgParser no longer needs the static block to
initialise its own resource bundle, Eclipse JDT will automatically pick
it up.
The version string was also updated to the new Eclipse merge commit
hash + date + "Java16".
TODO: Strip down properties file in order to only contain delta to
Eclipse.

AjBuildManager: use try with resources in 2 places
I was debugging something in ModuleTests, trying to find out if there
are resource leaks. They were not in this class but in FileUtil - see
next commit. However, the little refactoring here does not hurt either.

Reports on declarations of Collection variables made by using the collection class as the type, rather than an appropriate interface.
Signed-off-by: Lars Grefer <eclipse@larsgrefer.de>
Reports Collection.addAll() and Map.putAll() calls after instantiation of a collection using a constructor call without arguments. Such constructs can be replaced with a single call to a parametrized constructor which simplifies code. Also for some collections the replacement might be more performant.
Signed-off-by: Lars Grefer <eclipse@larsgrefer.de>
There are two styles to convert a collection to an array: either using a pre-sized array (like c.toArray(new String[c.size()])) or using an empty array (like c.toArray(new String[0]).
In older Java versions using pre-sized array was recommended, as the reflection call which is necessary to create an array of proper size was quite slow. However since late updates of OpenJDK 6 this call was intrinsified, making the performance of the empty array version the same and sometimes even better, compared to the pre-sized version. Also passing pre-sized array is dangerous for a concurrent or synchronized collection as a data race is possible between the size and toArray call which may result in extra nulls at the end of the array, if the collection was concurrently shrunk during the operation.
