> SC: constructor reference calls the constructor through the meta-class
> instead of directly
> ------------------------------------------------------------------------------------------
>
> Key: GROOVY-12488
> URL: https://issues.apache.org/jira/browse/GROOVY-12488
> Project: Groovy
> Issue Type: Improvement
> Components: Static compilation
> Affects Versions: 6.0.0
> Reporter: Scott Murphy Heiberg
> Priority: Major
>
> Under {{@CompileStatic}}, a constructor reference such as {{Made::new}} is
> implemented by a synthetic method {{ctorRef$<method>$<n>}} on the enclosing
> class, which the LambdaMetafactory call site targets. That method is not
> statically compiled:
> {noformat}
> private static final Made ctorRef$ctorRef$0();
> 0: ldc class Made
> 2: invokedynamic init:(Ljava/lang/Class;)Ljava/lang/Object;
> 7: invokedynamic cast:(Ljava/lang/Object;)LMade;
> 12: areturn
> {noformat}
> So every call selects the constructor through the meta-class at run time,
> while other method references ({{String::length}}, {{Math::abs}}) link their
> target directly. In a GraalVM native image the constructor also needs
> reflection metadata although the code is statically compiled.
> The cause is
> {{StaticTypesMethodReferenceExpressionWriter.addSyntheticMethodForConstructorReference}}:
> it builds the constructor call without a target constructor and sets
> {{STATIC_COMPILE_NODE}} to false (there is a TODO for it).
> Proposed fix: select the constructor at compile time among the constructors
> visible from the enclosing class, matched against the functional interface's
> parameter types as for a constructor call expression, and call it directly.
> Keep the run-time selection when no single constructor matches
> (GROOVY-10971), for a protected constructor in another package, and for a
> protected or package-private constructor of a class compiled in another
> compilation unit, which may come from another class loader. As with other
> method references and with Java, the constructor is then chosen from the
> declared parameter types rather than the run-time argument types.
