Eric Milles reassigned GROOVY-10894:
------------------------------------
Assignee: Eric Milles
> Duplicate annotations on trait FieldHelper
> ------------------------------------------
>
> Key: GROOVY-10894
> URL: https://issues.apache.org/jira/browse/GROOVY-10894
> Project: Groovy
> Issue Type: Bug
> Components: Compiler
> Affects Versions: 4.0.8
> Reporter: Christopher Smith
> Assignee: Eric Milles
> Priority: Major
> Labels: regression
>
> The latest nightly (included with GRECLIPSE 4.9.0.v202301012233-e2206) has
> introduced a regression that appears to be the same bug as GROOVY-10553;
> JSR-303 annotations applied to a trait property are listed twice in the
> bytecode on both the field and the {{$get/$set}} methods, resulting in an
> {{AnnotationFormatError}} at runtime. Compiling with groovyc 4.0.7 produces
> clean bytecode, and rebuilding in Eclipse reintroduces the duplicate.
> Sample:
> {code}
> trait LocationRelated {
> @NotNull @Valid Location location
> }
> {code}
> In {{FieldHelper}} disassembly:
> {code}
> public abstract com.example.Location
> com_example_LocationRelated__location$set(com.example.Location);
> descriptor: (Lcom/example/Location;)Lcom/example/Location;
> flags: (0x0401) ACC_PUBLIC, ACC_ABSTRACT
> RuntimeVisibleTypeAnnotations:
> 0: #11(): METHOD_RETURN
> javax.validation.constraints.NotNull
> 1: #12(): METHOD_RETURN
> javax.validation.Valid
> 2: #11(): METHOD_RETURN
> javax.validation.constraints.NotNull
> 3: #12(): METHOD_RETURN
> javax.validation.Valid
> 4: #11(): METHOD_FORMAL_PARAMETER, param_index=0
> javax.validation.constraints.NotNull
> 5: #12(): METHOD_FORMAL_PARAMETER, param_index=0
> javax.validation.Valid
> 6: #11(): METHOD_FORMAL_PARAMETER, param_index=0
> javax.validation.constraints.NotNull
> 7: #12(): METHOD_FORMAL_PARAMETER, param_index=0
> javax.validation.Valid
> {code}
> (As a side issue, is there a particular reason these methods aren't marked
> synthetic? I'm not certain that would prevent the problem's actually
> surfacing in this case, but based on my reading of the Hibernate Validator
> code it might have. Not sure whether that's a positive or a negative, though.)
