Summary: Improve AnnotationLiteral for empty annotations
Project: CDI Specification Issues
Issue Type: Feature Request
Reporter: Mark Struberg
Annotation hashCode() and equals() operations are fairly expensive as they always invoke getDeclaredMethods() even if there are no such. And getDeclaredMethods involves the SecurityManager + wrapper classes + Exception handling + + +
That's horrible expensive.
In OWB I improved this by introducing an own base class for dynamic annotations which do not have any members:
The method returns a hardcoded String for toString(), returns hardcoded 0 as hashCode and the equals() method invokes the equals on the annotation type.
We might support this improvements directly in the AnnotationLiteral class or introduce a similar 2nd class especially for empty annotations?
