Crash on startup CreativeTabAbstractBase

[NCrashed]

Describe the bug On server/client startup I encountered a weird crash. WarpDrive cannot find ItemStack.EMPTY at runtime when constructing static fields.

Hot fix is to replace line at CreativeTabAbstractBase.java:12 to:

private ItemStack itemStack = new ItemStack((Item)null);

To Reproduce Start the server or client.

Expected behavior Clean startup.

Additional context The crash occurs on the client and on the server.

[LemADEC]

ItemStack.NULL comes from Forge if not Vanilla. This is probably a transformer issue triggered by another mod. authlib, Veinminer, ChatTweaks, etc. appears in those logs. Please provide a client side log with minimal mods.

[LemADEC]

At least Forge, IC2Classic, JEI, OreLib, CC:Tweaked, WanionLib are outdated in your setup. Try to reproduce with latest versions.
