> Running the unit test {{DefaultSatSolverTest.testSingleVersionResolution()}}
> once on Java 1.5 and 1.6 revealed a bug in {{DefaultSatSolver.solve()}} due

> The internal tweaks to the hash algos employed by the different JRE versions
> exhibited a non-deterministic ordering of the artifact metadata list.
