This is a first-pass attempt to limit matching of Vim9 and legacy-script
comments to the appropriate syntactic contexts.
Vim9-script comments are highlighted at top level in a Vim9-script file,
in all :def functions, and in all :autocmd and :commmand command blocks.
Legacy-script comments are highlighted at top level in a legacy script
file, in all :func functions and in the Vim9-script preamble before the
:vim9script marker command.
Fixes #13047, #11307 and #9587.

- Recognise a _record_ contextual keyword.
- Recognise _non-sealed_, _sealed_, and _permits_ contextual
keywords.
- Admit _$_ to keyword characters.
- Group _abstract_, _final_, _default_, _(non-)sealed_
(apart from _(non-)sealed_, the incompossibility of these
modifiers calls for attention).
- Remove another _synchronized_ keyword redefinition.
I have also replaced a function with an expression. Before
patch 8.1.0515, it should have been declared :function! to
work with repeatable script sourcing; there is less to worry
about with an expression.

functions (#14348)
Currently, the overriding object method definitions are
matched as vimFunctionError (:help builtin-object-methods,
v9.1.0148).
For example:
------------------------------------------------------------
vim9script
class Test
def string(): string
return "Test"
enddef
endclass
echo string(Test.new()) == Test.new().string()
------------------------------------------------------------
Instead, let's introduce a new syntax group vimMethodName
and make these methods its members. In order to emphasise
the link between the overriding methods and the overridden
functions for highlighting, vimMethodName is linked by
default to vimFuncName.

Also:
- Refine comment matching (javaComment{Error\ and,Start}).

- Match the nullary method parens in javaDocSeeTagParam.
- Improve the boundary patterns for summary sentences of
documentation.
> This sentence ends at ... or at the first tag (as defined
> below).
There are Java documentation tags (@) and there are HTML
tags (<?>) (with Markdown looming large; see JEP 467). With
block tags, e.g. @param, @return, @see, we begin another
documentation "sentence" whether or not the author has
terminated the summary sentence with a period; with
.<!-- -->, we may follow abbreviations, enumerations,
initials, (but instead consider @literal or ) _within_
the summary sentence. On the other hand, inline tags, e.g.
@code, @link, @literal, should not terminate the summary
sentence.

Remember that ‘code fragments are typically Java source
code, but they may also be fragments of properties files,
source code in other languages, or plain text.’ Therefore,
with these changes, markup tags are highlighted in the Java
source files (as external snippets) and in the {@snippet}
tags.
Also:
- Improve matching of the multi-line {@code} documentation
tag with any contained balanced braces.
- Recognise the {@literal} documentation tag.
- Highlight stray blanks in comments.

Not all programming languages support comments; without such
support, the TEST_SETUP functionality that offers embeddable
Vim Ex commands may no longer be applicable.
We can achieve similar functionality by storing Ex commands
in a Vim file with its basename matching the basename of the
test file, and having this Vim file sourced, and then having
the test file loaded and tested. When such a Vim file would
be used for a language that has comments and whose matching
test file has embedded TEST_SETUP lines, we will accommodate
it by letting the TEST_SETUP lines augment and/or overrule
sourced configuration.
Further details can be found in the discussion thread at
https://github.com/vim/vim/discussions/14117.

Currently, the very same syntax file for which a test can
be written is the only place where global variables can be
defined so that the file parts guarded with such variables
can be read during screen dump generation. This approach
would lead to littering the syntax file with test-related
queries.
Instead, we could borrow the idea of comment-based mechanism
for test setup from the indent test runner. With it, the
first 20 lines of each test file would be ALWAYS scanned in
search of the TEST_SETUP markers and, when found, the part
between the end of the marker and the end of the line would
be treated as a Vim Ex command.
Note that with these changes, runtime/defaults.vim is no
longer sourced for screen dump generation; however, some of
its functionality is reintroduced.

- Limit blob literals to an even number of hexadecimal digits and

- Match octal numbers.
The current version unsuccessfully attempts to match a leading '-' as
part of the float literal. It's actually parsed as part of the literal
for all numbers but the syntax file hasn't matched it like that for a
long time and highlights negative numbers as UNARY-MINUS NUMBER. This
will be fixed when better expression matching is implemented.

As this is encouraged in the referenced JEPs, "to visually
distinguish a string template from a string literal, and
a text block template from a text block", the default
colours for java\%[Debug]StrTempl are made distinct from
java\%[Debug]String.
According to §3.2 Lexical Translations (JLS, c. 1996 or any
more recent version), line terminators, white space, and
comments are discarded before tokens are accepted. Since
a template expression comprises a template processor, a dot,
and a template, it may be visually appealing to break up
its head across a few lines whenever its tail already spans
multiple lines. Curiously, no allowance for it is made in
the distributed tests for OpenJDK 21; the proposed regexp
patterns take in consideration a line terminator and white
space after a dot.

Also:
- distinguish _yield_ when used as a contextual keyword from
when used qualified as a method or a method reference (as
can be seen in testdir/input/java_switch.java, variables
and method declarations named _yield_ will be recognised
as the namesake keyword--consider picking other names for
variables, and defining g:java_highlight_functions to have
method names painted; since _yield_ statements can have
trailing parens, they must be recognised as statements,
for only qualified _yield_ method calls are supported);
- recognise grouped _default_ _case_ labels;
- describe primitive types for _case_ labels (JLS, §14.11,
§3.10.1);
- recognise some non-ASCII identifiers (see javaLambdaDef,
javaUserLabel) (further improvement for better recognition
of identifiers will be arranged in a separate PR).
Because the arrow '->' is used in two kinds of expressions,
lambda (abstractions) and _switch_, necessary changes were
made for the recognition of either (and further improvement
touching lambda expressions will be separately arranged).
Because 'default' is used for instance method declarations
in interfaces and in _switch_ labels, necessary changes were
made for the recognition of either (and further improvement
touching method declarations will be separately arranged).
Finally, it deemed appropriate to put 'yield' in the syntax
group of javaOperator rather than javaStatement, for its
member 'var' is also another contextual keyword (e.g., this
is valid syntax: "var var = var(test.var);").

The whole testdir/runtest.vim is a bit of a mess. So this is an attempt
to improving the current state. First of all, let's move most of the
code into a single RunTest() function so that it's easier to run this
manually.
Then, let's add the possibility to customize filetype specific tests by
applying filetype specific options. We will make use of it in the next
commit, where the provided java file uses tabs, which cause line
wrapping which will then cause the scrolling to miss some lines when
redrawing (see #14105)

command (#14050)
With the arrival of Vim9 classes, the syntax must allow for
_new_ constructors; multiple constructor definitions are
supported for a class, provided distinct suffix-names are
used. Currently, the defined constructors match either
vimCommand or vimFunctionError (for any newBar).
For example:
------------------------------------------------------------
vim9script
class Foo
def new()
enddef
def newBar()
enddef
endclass
------------------------------------------------------------
Since every constructor is required to bear a lower-cased
_new_ prefix name, it should suffice to distinguish them
from functions, and so there are no new highlight or syntax
groups introduced.
