Abstract

This paper introduces our ongoing study on type safety of the type relaxed weaving mechanism in the presence of two Java 5 features, namely covariant return types and generics. We point out additional conditions that are necessary to ensure type safety, which can be checked by a slightly modified type checking rules for the type relaxed weaving.
