I will investigate.
I could not reproduce. I fixed the possible class cast exception. Code is released. Reopen if you see it again.
Bug was to cast an AbstractMethodDeclaration into an AnnotationMethodDeclaration if it was not an instanceof MethodDeclaration (when computing the return type). This would always cause a ClassCastException for Clinit and ConstructorDeclaration. Verified (in I20041214-2000) that the fix consists in returning null for the return type of Clinit and ConstructorDeclaration.
