Updated FML:
MinecraftForge/FML@6f3da9736531153629fb4213e3b2cae776bfb50a Don't throw an exception if the scala adapter find a java proxy. I may add some distinguishers to @SidedProxy so you know which mod it's for.
MinecraftForge/FML@59fe905695421a5be9370b0009ef794abaaf75bb Don't continue trying to send events to mods that depend on errored mods.
