We discuss integrating abstract data types (ADTs) in the KeY theorem prover by a new approach to model data types using Isabelle/HOL as an interactive back-end, and translate Isabelle theorems to user-defined taclets in KeY. As a case study of this new approach, we reason about Java’s Collection interface using histories, and we prove the correctness of several clients that operate on multiple objects, thereby significantly improving the state-of-the-art of history-based reasoning.
