This module must be a relic from a test runner module once existing
during the Ant build era, but transferred and kept alive in the Maven
build. Actually, it almost doubles build time by running virtually all
tests in all modules again when doing 'mvn test' from the project root.

For now I only removed the module from the root POM, leaving behind
comments there, in the module POM and in the now @Deprecated class

Several LTW tests using class TestServer failed on my machine because
there was a hard-coded project base directory name 'org.aspectj' in the
class. This class has several other problems, but my quick fix for now -
I did not want to rename my project base directory - was to match on a
regex '(?i)(org[.])?aspectj' now. That also works for my root directory
'AspectJ'.

I also moved the code determining the project dir into a protected
(hence testable) method and added a sanity test case checking if the
directory can be determined. If not, the test will fail with a rather
lengthy warning to developers about the need to have a matching project
root folder.

The line in which warnings like "Archived non-system classes are
disabled because the java.system.class.loader property is specified"
appears can start with e.g."OpenJDK 64-Bit Server VM" or "Java
HotSpot(TM) 64-Bit Server VM". Therefore, an exact match on the former
worked on Linux, but not on Windows, or maybe the difference is
generally between Oracle and OpenJDK. anyway, I use Oracle on Windows
and my build failed. Now it is fixed because I made the match more
generic using a regex.

I also removed a now obsolete check for the occurrence of the stripped
line in test "JDK14 LTW with XML".

- 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

WARNING: Please avoid line breaks in manifest values! They are passed on
like this: Assembly Plugin -> Plexus Archiver -> JRE java.util.jar
.Manifest.write(OutputStream).

The JRE Manifest class inserts hard line breaks always after 72
characters, no matter if those 72 characters contain line feeds, tabs or
spaces. Hence, it can happen that unwanted blank lines end up in the
middle of a manifest section, making the manifest invalid. Calls like
e.g. 'java -cp aspectjtools.jar org.aspectj.tools.ajc.Main' can then
fail with the absolutely unexpected error 'Could not find or load main
class org.aspectj.tools.ajc.Main'.

In IntelliJ IDEA you can deactivate wrapping text inside XML tags like
this: "File | Settings | Editor | Code Style | XML | Wrap text -> off"

The problem occurs in Maven Assembly in versions higher than 2.2. More
exactly, it occurs in Plexus Archiver after in more recent versions it
switched to using the JRE Manifest class.

TODO 1: Either add a test step in phase 'verify' doing something like
this:

new Manifest(new FileInputStream("MANIFEST.MF"));

This would lead to "IOException: invalid header field (line xy)" in case
of an invalid manifest file.

TODO 2: Or file a JRE bug at Oracle or OpenJDK, wherever appropriate.

Some Java 14 text block tests failed on Windows because a
StringTokenizer was used to split by LF, but the Windows line
separator is CR+LF. Because a multi-line string ending with CR+LF is
printed via 'System.out.println' in the test code, another CR+LF is
added to the output, resulting in trailing CR+LF+CR+LF. Hence, between
the two LFs, the tokenizer actually found an additional line consisting
of CR (only on Windows, of course). Despite each line token actually
containing a trailing CR token, that did not matter much because
'String.trim' was used everywhere before comparing values.

Anyway, the improved OutputSpec uses text.trim().split("\\s*\n\\s*"),
which takes care of leading/trailing whitespace both around the whole
output and for each separate line.

Some tests in ajc150.xml and ajc190_from150.xml contain '<weave ...>'
build steps with 'xlintfile="..."' parameters. Those parameters were
passed through to Java and aspect code building steps, but not to the
final weaving step, sometimes leading to spurious "type not exposed to
weaver" warnings which occurred for some local and CI builds, but not
always. Very strange indeed. Anyway, by making method
WeaveSpec.buildWeaveArgs() pass on this parameter, the tests seem to run
reliably now.

TODO: Why does Ajc report that warning if the application JAR is on the
inpath and the aspect JAR is on the aspectpath? Is it because a marker
annotation is defined within the aspect JAR? But actually, that should
not matter, especially not work once and fail at other times. I guess
there is a class loading order problem or similar involved.

When trying to find out why ajc150.xml and ajc190_from150.xml look
almost identical, I found out that only in many cases the 190 version
has '-option="1.9"' set where in the 150 version it was '-option="1.9"'.

Unfortunately, in both files source/target versions are not set at all
in many places, which looks unintentional. I tried to search & replace
all relevant '<compile ...>' commands for 190 first, then ported back to
150. Only cases in which clearly compiling to an older version like 1.3
or 1.4 is necessary were left like before.

I am expecting missing or false Java target versions in many other of
the legacy XML test suites. For now, I am just committing these two.
