They are called SDS paths (Specular-Diffuse-Specular) and not even normal bidirectional path tracing can render them. The are very hard to render light paths.
You need to use the under development v2.3 and to enable PhotonGI caustic cache like in this test scene: viewtopic.php?f=5&t=1449&p=18410#p18388 (the under water caustics are SDS paths).
