modpack Modpack won't start after loading

[Frechy__]

Hello!
My problem is, when i start a modpack (now the Ultra Modded-Survival) it starting loading but after it, crashing with no message. I give 4GB RAM for the Mods (so i have 64-bit Java of course).
I put the crashing report to the attached file. I hope someone can help. ^^ Have a good weekend.

One of the mods (Jurassicraft) has an auto-updater which is somehow broken these days. The only thing that helps is manually updating to a newer version of Jurassicraft and LLibrary.
