Introduce a new API variable "g:java_syntax_previews" whose
value must be a list of syntax preview feature numbers.
Enumerate the currently supported numbers in a table at the
end of the documentation entry for "ft-java-syntax".
Also, disable the recognition of String Templates. Despite
the withdrawal of this preview feature in its proposed form
from the upcoming JDK 23 release and the fact that the JDK
22 release is coming to EOL this September, an earlier
iteration of this preview feature was included in JDK 21
(LTS) whose EOL is projected to fall due in late 2028 and,
therefore, retain the current implementation.
Define "g:java_syntax_previews" and include number 430 in
its list to enable the recognition of String Templates:

In the presence of parameterised types whose names begin
with a capital letter and end with a less-than sign "<" that
introduces a type argument or a list of comma-separated type
arguments, followed by a greater-than sign ">", a variable
"g:java_highlight_generics" can be defined to have some
components of such types uniformly coloured (by picking
highlight groups for javaGenericsC{1,2}, javaWildcardBound).
For example,
------------------------------------------------------------
java.io.InputStream stream = java.io.InputStream.nullInputStream();
java.util.function.Function<String,
java.util.function.BiFunction<String, String, String>> updater =
property -> (oldValue, newValue) -> oldValue;
java.util.logging.LogManager.getLogManager()
.updateConfiguration(stream, updater);
------------------------------------------------------------
Note that the diamond form and explicit type arguments do
not qualify for this kind of recognition.
For example,
------------------------------------------------------------
new java.util.HashSet<>().<String>toArray(new String[0]);

Also:
- Restore the capability to mark as an error braces nested
in parens with g:javaInParen.
- Try not to fold top-level-type bodies. (Defining multiple
package-private top level types in a single source file is
not recommended as it can impose order among compilation
units; so it is assumed that only one such top level type
is usually defined.)
- Compose ‘method header’ highlighting and block braces
folding.
- Do not highlight block braces whenever ‘method header’
highlighting is requested.
This bundling of ‘method headers’ and block braces for
highlighting can be traced back to Vim v5.0; however, no
comment or documentation entry conveys any justification.
For example, it is hard to discover the connection between
block braces for "while", "if", etc., statements and method
body block braces. The former behaviour can be attained in,
e.g. ~/.vim/after/syntax/java.vim:
------------------------------------------------------------
if exists("g:java_highlight_functions")
syn clear javaBlock javaInParen
syn match javaBlockOther "[{}]"
syn region javaBlock transparent matchgroup=javaBlockStart
\ start="\%(^\|^\S[^:]\+\)\@120<!{" end="}" fold
hi def link javaBlockStart javaFuncDef
hi def link javaBlockOther javaBlockStart
if exists("g:java_mark_braces_in_parens_as_errors")
syn match javaInParen contained "[{}]"
endif

There is a flaw in the current implementation that has been
exacerbated around v5.2. It lies in the recognition of all
three indentation styles simultaneously: a tab, two space,
and eight space character(s). With it, it is not uncommon
to misidentify various constructs as method declarations
when they belong to two-space indented members and other
blocks of a type and are offset at eight space characters or
a tab from the start of the line.
For example,
------------------------------------------------------------
class Test
{
static String hello() { return "hello"; }
public static void main(String[] args)
{
try {
if (args.length > 0) {
// FIXME: eight spaces.
System.out.println(args[0]);
} else {
// FIXME: a tab.
System.out.println(hello());
}
} catch (Exception e) {
throw new Error(e);
}
}
}
------------------------------------------------------------
------------------------------------------------------------
:let g:java_highlight_functions = 'indent'
:doautocmd Syntax
------------------------------------------------------------
A better approach is to pick an only indentation style out
of all supported styles (so either two spaces _or_ eight
spaces _or_ a tab). Note that tabs and spaces can still be
mixed, only the leading tab or the leading run of spaces
matters for the recognition. And there is no reason to not
complement the set of valid styles with any number of spaces
from 1 to 8, inclusively.
Please proceed with the necessary change as follows:
- rename from "indent" to "indent2" for a 2-space run;
- rename from "indent" to "indent8" for an 8-space run;
- continue to have "indent" for a tab run;
- define an "indent" variable with a suffix number denoting
the preferred amount of indentation for any other run of
spaces [1-8].
As before, this alternative style of recognition of method
declarations still does not prescribe naming conventions and
still cannot recognise method declarations in nested types
that are conventionally indented.
The proposed changes also follow suit of "style" in stopping
the claiming of constructor and enum constant declarations.

- Request the new regexp engine (v7.3.970) for [:upper:] and
[:lower:].
- Recognise declarations of in-line annotated methods.
- Recognise declarations of _strictfp_ methods.
- Establish partial order for method modifiers as shown in
the MethodModifier production; namely, _public_ and
friends should be written the leftmost, possibly followed
by _abstract_ or _default_, or possibly followed by other
modifiers.
- Stop looking for parameterisable primitive types (void<?>,
int<Object>, etc., are malformed).
- Stop looking for arrays of _void_.
- Acknowledge the prevailing convention for method names to
begin with a small letter and for class/interface names to
begin with a capital letter; and, therefore, desist from
claiming declarations of enum constants and constructors
with javaFuncDef.
Rationale:
+ Constructor is distinct from method:
* its (overloaded) name is not arbitrary;
* its return type is implicit;
* its _throws_ clause depends on indirect vagaries of
instance (variable) initialisers;
* its invocation makes other constructors of its type
hierarchy invoked one by one, concluding with the
primordial constructor;
* its explicit invocation, via _this_ or _super_, can
only appear as the first statement in a constructor
(not anymore, see JEP 447); else, its _super_ call
cannot appear in constructors of _record_ or _enum_;
and neither invocation is allowed for the primordial
constructor;
* it is not a member of its class, like initialisers,
and is never inherited;
* it is never _abstract_ or _native_.
+ Constructor declarations tend to be few in number and
merit visual recognition from method declarations.
+ Enum constants define a fixed set of type instances
and more resemble class variable initialisers.
Note that the code duplicated for @javaFuncParams is written
keeping in mind for g:java_highlight_functions a pending 3rd
variant, which would require none of the :syn-cluster added
groups.
