------------------------------------
Summary: Java8 does not load enum values into annotation attributes
Key: GROOVY-10352
URL: https://issues.apache.org/jira/browse/GROOVY-10352
Project: Groovy
Issue Type: Improvement
Components: Compiler
Affects Versions: 4.0.0-beta-2
Reporter: Eric Milles
Assignee: Eric Milles
Consider the following:
{code:groovy}
@AnnotationCollector(mode = AnnotationCollectorMode.PREFER_EXPLICIT_MERGED)
@interface Example {
}
{code}
{code:groovy}
@Example
class Sample {
}
{code}
When the compiler accesses the annotations of Example through the {{ClassNode}}
Sample, the {{AnnotationCollector}} {{mode}} attribute is null. This can be
problematic for AST transformations which rely on the Groovy model for the
annotation metadata.
In my real-world example, I had a {{record}} type, which has the implicit
annotation {{RecordType}}. When I added an explicit {{TupleConstructor}}
annotation, the attributes were not merged, so I received duplicate processing
of {{TupleConstructor}} and therefore duplicate constructors.
