An apparatus, computer system program product and method implement self-healing functionality in a cross development environment to maximize the availability and minimize interoperability problems between disparate software development environments that are coupled to one another via such an environment. In particular, dynamically-modifiable mapping data structures are used to interface multiple software development environments with one another, such that modifications may be made to such data structures in response to modifications made in the underlying software development environments and thereby maintain interoperability between such software development environments.
