------------------------------------------
Summary: 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
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
