runtime(java): Improve the recognition of the "style" method 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.
