------------------------------
> STC can't find method reference for property with annotation
> ------------------------------------------------------------
>
> Key: GROOVY-10157
> URL: https://issues.apache.org/jira/browse/GROOVY-10157
> Project: Groovy
> Issue Type: Bug
> Components: Static Type Checker
> Affects Versions: 3.0.8
> Reporter: Christopher Smith
> Assignee: Eric Milles
> Priority: Major
> Labels: annotations
>
> I am having difficulty reducing this to a minimal example, but it seems (1)
> reliably reproducible with groovyc and (2) intermittent(?) with GRECLIPSE.
> Method references (with {{.&}}) to getters are inconsistently producing
> errors of the form
> {code}
> Cannot find matching method com.example.IdentityRecord#getEmail.
> {code}
> The property in question is defined simply as {{String email}}, and {{javap}}
> produces the entirely mundane
> {code}
> public java.lang.String getEmail();
> Code:
> 0: aload_0
> 1: getfield #94 // Field email:Ljava/lang/String;
> 4: areturn
> {code}
> What is baffling me is that this does not occur on all properties. The
> properties on which it appears are ones where I have JSR-303 annotations
> (i.e., markers but nothing that triggers an ASTT), but the error persists
> _even after commenting the annotation and its import_, both in groovyc and
> GRECLIPSE. Identical properties without annotations never trigger the error.
> It _appears_ that the error only appears when both the POGO and the class
> trying to define a method reference on it are in the compilation unit; in
> Eclipse only, explicitly compiling the record class and then triggering a
> recompile by saving the service class works, but doing a project clean and
> rebuild produces the error.
> I believe that this may be able to reproduce:
> {code}
> import javax.validation.constraints.Email
> @CompileStatic
> class Record {
> @Email String email
> }
> @CompileStatic
> class Service {
> List<String> emails(List<Record> records) {
> records.collect(Record.&getEmail)
> }
> }
> {code}
