• [ x] This is a mod incompatibility. If I do this in vanilla Forge with only Et Futurum Requiem installed, it works normally.

Version number of Et-Futurum-Requiem (IMPORTANT)

2.4.2

Describe the issue (IMPORTANT)

Looking up the uses for any item that would be used to upgrade a shulker box (iron, obsidian, gold, etc.), or the shulker box itself in NEI causes the game to crash with the above error. It seems to be an issue with the way the Iron Chests integration is happening. I can't reproduce this in instances with or without Iron Chests in it; only when adding Et Futurum Requiem to Blightfall 3.0.1-CE does this happen, which does not have Iron Chests in its mod list

Uhm i dont know if you noticed, but the crash happens while the Item is rendered, which means the Game has to have already put all the "icon" Arrays into place at this point.

Also it is the "diamond_obsidian_upgrade" that specifically is crashing according to the Logs. Weirdly enough when I look into that Class it does not have anything suspicious in it, it SHOULD assign the icon Array, but for some reason it does not, which leads me to believe that this Item is NOT in the ItemRegistry, and therefore WONT have registerIcons called ever, and therefore will crash the instant you try to render it.

Remembering IronChests is NOT installed, yet the Upgrade Item exists at all, means something is broken with your way to detect IronChests, and look at that I think I found it!

https://github.com/Roadhog360/Et-Futurum-Requiem/blob/master/src/main/java/ganymedes01/etfuturum/recipes/ModRecipes.java#L862

This Line is the Issue! Literally everywhere else you check EtFuturum.hasIronChest && ConfigBlocksItems.enableShulkerBoxesIronChest but HERE you do not! Resulting in a Crafting Recipe for an unavailable Item being registered, which results in this Error!

And since this is caused by the LACK of a Mod being installed, I dont think that makes it a Mod Conflict :P

Even without NEI installed you could cause this if you tried crafting the Upgrade Item by looking up its Recipe on a Wiki or cheatsheet or something. ;)

I can't reproduce this so this is a mod conflict. I fixed some different issues regarding them, so try the latest CI and if that fixes it I can close this.

I can tell you right away this is NOT a mod conflict. What is likely happening is that something returns an illegal value somewhere within EFR Code. In this case it is a very clear cut Issue, see:

https://github.com/Roadhog360/Et-Futurum-Requiem/blob/master/src/main/java/ganymedes01/etfuturum/items/ItemGeneric.java#L39

The Array "icons" is clearly null because it did not get assigned for one of the things you recently added.

Edit: Also the Array "types" cannot be null, so that one is not at fault, since it is assigned with a ... parameter which only ever nets you a zero length array and not a null.

Also as a general rule of thumb, if the first line underneath a Nullpointer Exception is part of YOUR code, it is automatically on you to fix it, and cannot be blamed on other Mods.

It has to be a mod conflict because NEI nor creative causes it = mod causes it
Icons is assigned in registerIcon where it should be so it is not possible for it to be null unless a mod erroneously calls functions too early when it shoudn't. It is the same code for all ItemGeneric types so it can't just be an item I recently added. If it was tha then this would have happened in the past.

I don't see how recipes would cause this crash but ok

Ah nice. ^^

Also you know that if the Recipe outputs an Invalid Item, and you just so happen to know the Recipe from memory and try to craft it, the moment the invalid Output shows in the Vanilla Crafting Table Output Slot it will crash with this same Error.

That is how it happens, and NEI makes it just slightly more visible since it has the Recipe List and all.

It would also happen if we had that "brand new" Vanilla Recipe Book Feature. (but that vanilla recipe book is a performance nightmare for modded Minecraft)

But the Iron Shulker Upgrade is fixed now, at least should very much be fixed now.
