Abstract: It is shown that the geodesic rays constructed as limits of Bergman geodesics from a test configuration are always of class $ C^{1,\alpha}$, $ 0<\alpha<1$. An essential step is to establish that the rays can be extended as solutions of a Dirichlet problem for a Monge-Ampère equation on a Kähler manifold which is compact.
