Whenever I try to join node 4 on infinity normal, my Minecraft crashes. I believe it is because of an error in the chunk that I am in. It doesn't crash when i join other nodes or the lobby, and I wasn't having problems until i was flying around looking for something, then all the sudden I crashed and continue to do so.
It seems to be an error with Thaumcraft Golems for some reason. Next time, however, please put this info in a pastebin. Not everyone enjoys having to download a file in order to view it.
Thaumcraft uses some stuff that is in java 8 but not in java 7. So you should be fine if you update to java 8.
Please attempt to recreate the crash and paste the crash-report to pastebin or ghist. EDIT: 30MAY2016 Closing due to no response form player
