Launching from Twitch client, the latest release has an intermittent failure with an ArrayIndexOutOfBoundsException.
It happens at forestry.storage.models.ModelCrate.bake(ModelCrate.java:76)

Expected Behavior

Umm. It shouldn't crash.

Current Behavior

Crashes with an ArrayIndexOutOfBoundsException.

Possible Solution

Sometimes restarting it works.

Steps to Reproduce

1. Start All the Mods 3 from the Twitch Client using the native launcher
2. Wait for the crash
3. I'm also using Sphax resource packs, which may be contributing to the issue.
4. I maxed out memory (12G).

Detailed Description

I would start by updating your java and making twitch not use the native launcher. This link has a guide of how to step through this. https://www.reddit.com/r/allthemods/comments/968r4k/how_to_fix_modpack_wont_load_fps/

Yeah, I usually don't use the native launcher. Switching to it seemed to make it a little more stable. I'm already using the latest Java 8.
FYI - Removing the Sphax resource packs seems to help.

From the log that you gave, it shows java 1.8.0_51 being used, that's why I mentioned it. Even if you have the latest java, minecraft won't use it if the native launcher is being used. it instead uses the prepackaged version it has.

Okay, I switched over to the jar launcher and used the recommendations in the reddit link above. (Surprised the java packaged with the twitch client is that old). I used the recommended command switches and added optifine also.
Started up okay, so I added the Sphax resource packs back in.
Crashed in the exact same place (at forestry.storage.models.ModelCrate.bake(ModelCrate.java:76).
Gonna have to run without Sphax, I guess.
Seems to start okay about every other time with Sphax. I removed the resource packs and it started up okay without them a couple of times.
Still pretty anecdotal, but maybe enough info to chalk it up to a problem between forestry and sphax.

Nope, spoke too soon. Started it up a third time and it failed in the exact same place.

Can you post a new log.

Sorry, I didn't save that last one. I'll post another as soon as it happens again.

Sorry for the delay. Finally happened again. Had been pretty stable for a while even after I added the Soartex Fanver Modded and Soartex Fanver Vanilla resource packs.
Here's the log:

Again, ArrayIndexOutOfBoundsException in the exact same place.

And here it is again with no resource pack and a fresh modpack install.

I'm going to try disabling foamfix since it shows up in the stack trace.

Finally found what I was looking for. Either removing foamfix, or replacing the one that is in (anarchy) with lawful should work as well.

Yeah, removing foamfix works...okay...as long as you don't have any resource pack. I'll give foamfix lawful a try.

Don't see any recent lawful builds. So I set B:forceDisable=true in the foamfix config, which is supposed to have the same effect as using lawful.
Should this bug report be posted elsewhere? Is this a foamfix bug, then?

I think it's already known about, but can double check
