Improve text matching in OutputSpec, fixing some failing Windows tests
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.

Fix: WeaveSpec no longer ignores the '-Xlintfile' parameter
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.

Replace directory separator '/' and surrogate path separator ',' by
platform-specific separators File.separatorChar and
File.pathSeparatorChar, respectively. Also make sure that replacement
occurs during write access, not read access. This was handled
differently in both sibling classes.
I am not sure if that helps to fix any Linux CI tests, but it is worth a
try.

Reports on declarations of Collection variables made by using the collection class as the type, rather than an appropriate interface.

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.

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.

Collections.sort() can be replaced with List.sort()
Reports calls to Collections.sort(list, comparator) which could be replaced with list.sort(comparator).

Reports the copying of array contents to a collection where each element is added individually using a for loop. Such constructs may be replaced by a call to Collection.addAll(Arrays.asList()) or Collections.addAll().

Reports "unboxing", e.g. explicit unwrapping of wrapped primitive values. Unboxing is unnecessary under Java 5 and newer, and can be safely removed.

'String.indexOf()' expression is replaceable with 'contains()'
