Lessons from verifying legacy Java code for C++ specification & verification

David Cok

Legacy code is typically written with no regard for specification and verification. Consequently verification tools applied to legacy code must support most language features and be able to scale to the size and scope of industrial software. This talk will use case study examples from a verification project targeting industrial Java code to demonstrate both how verification of features in Java 8 was achieved and what challenges still remain for such projects. Then we will illustrate how the lessons learned from that project are informing the design of a specification language for C++.
