  Spin in Java (SpinJa) is an explicit state model checker for the Promela
modelling language also used by the SPIN model checker. Designed to be
extensible and reusable, the implementation of SpinJa follows a layered
approach in which each new layer extends the functionality of the previous one.
While SpinJa has preliminary support for shared-memory model checking, it did
not yet support distributed-memory model checking. This tool paper presents a
distributed implementation of a maximal accepting predecessors (MAP) search
algorithm on top of SpinJa.
