After launching the game, the modloader gets without problem to step 5/7 and then freezes on buildcraft. In the logs, the following is spammed:

[18:37:03] [Client thread/WARN] [net.minecraft.profiler.Profiler]: Something's taking too long! 'root.reload.contents_page.add_default.buildcraft/lib/client/guide/entry/PageEntryItemStack.itr_search' took aprox 766.8726 ms

If I wait around 30 minutes, the game finally crashes and spits out the following crashlog: https://gist.github.com/k-atze/a9d1dd48f104cba975944c0740fdbbb7

I've re-installed Java, triple checked it is 64-bit and JRE v8, reinstalled all mods from scratch, I've also added more RAM as suggested in MC-23484.
