Chunk refresh crash report.

[BrickVoid]

I received a crash report about Minecraft when attempting to refresh chunks with Shift-F3+A the report had the following text and a lot of crash report details which I've removed due to the length:

---- Minecraft Crash Report ----
// Oh - I know what I did wrong!

Time: 20/02/13 8:43 PM
Description: Unexpected error

java.lang.ArrayIndexOutOfBoundsException: -1

Is this to do with Minecraft or a mod in the Mindcrack FTB modpack, and should this be reported here, or to the Mojang bug report site?

Cheers ...

I get this exact same bug just by trying to see the graph with Shift+F3. I'm using the latest version (5.1.1) of the Direwolf20 pack though. I'm sure it isn't just Mindcraft, but yet I have no idea which mod(s) could be causing it. I was in an Extrabiomes biome at the time though, and now that I look more closely I see "HookProfiler" in one of the lines. This, I believe, might indicate a problem with Forge itself, as they use "world hooks" or something to that effect to generate certain structures and make various blocks valid as beacon bases and multiblock components. Whatever the case, it probably isn't just Minecraft, as I never had this problem on version 4.x.x. My advice would just be to wait a few more days. After all, several modders seem to be working pretty fast these days. KingLemming has internally overhauled Thermal Expansion. chickenbones has updated all of his mods and given us ender tanks at last. Soaryn has been talking about some sort of world update to XyCraft for about a week now, not to mention that he's making it modular to prevent/shorten future delays. Even Eloraam is "Back on RP full-time now." No, I'm not kidding. She tweeted four times yesterday. It all adds up to a fair amount of work for the FTB guys. Considering that they're just making sure all is well with the packs before releasing them to the public though, I think I can live with the few bugs and without a few features for a few more days. But soon... very soon...

It's Minecraft, not that which you wrote above.

For what it's worth, I can vaguely recall seeing this same chunk loading error happening in vanilla Minecraft, before I got into FTB, but with the way bug reports seem to be described I have a hard time finding reports on Mojang's bug tracker that actually resemble the same bug I'm experiencing.

I have a big feeling that it's something to do with the way Minecraft handles memory allocation and all of the extra information being squeezed into loaded chunks for modded Minecraft isn't helping the client and server. What would be interesting to find would be something that can be added to both vanilla and modded Minecraft installations that would allow to directly track chunk loading issues. I know the F3 debug screen is available but I'm talking about finding something much more direct and which can show in real time when the load gets too much for the client server, and what causes it.
