Brittle Modifier (TCon Compat) causes server crash when on 1 durability

[CrafterDaemon]

In TraitBrittle.class,

The crash is happening because of this line:

Integer damageDone = random.nextInt(Math.min(5, durability - 1));

The problem:
When durability = 1:

• durability - 1 = 0
• Math.min(5, 0) = 0
• random.nextInt(0) -> IllegalArgumentException: bound must be positive

Random.nextInt(n) requires n > 0. You can't call nextInt(0).

fix:

public void beforeBlockBreak(@Nonnull ItemStack tool, @Nonnull BreakEvent event) {
   Block block = event.getState().func_177230_c();
   if (block.func_176223_P().func_185904_a() == Material.field_151576_e) {
      Integer durability = ToolHelper.getCurrentDurability(tool);
      if (durability > 1) {  // Add this check
         Integer damageDone = random.nextInt(Math.min(5, durability - 1));
         ToolHelper.damageTool(tool, damageDone, event.getPlayer());
      }
   }
}

or you can just do

Integer maxDamage = Math.max(1, Math.min(5, durability - 1)); // Ensure at least 1
Integer damageDone = random.nextInt(maxDamage);

Found this while working on my modpack, thought I should report it.
