reason

at EntityHelmBrakerManager.java:286

if(!blade.isEmpty()){
    NBTTagCompound tag = ItemSlashBlade.getItemTagCompound(blade);
    for(Entity curEntity : list){
        //curEntity.hurtResistantTime = 0;

        if(thrower instanceof EntityPlayer){
            ItemSlashBlade itemBlade = (ItemSlashBlade)blade.getItem(); // if blade disappeared, this cast will cause uncaught exception
            itemBlade.attackTargetEntity(blade, curEntity, (EntityPlayer)thrower, true); // may break blade
        }
        else{
            DamageSource ds = new EntityDamageSource("mob", this.getThrower());
            curEntity.attackEntityFrom(ds, 10);
            if(!blade.isEmpty() && curEntity instanceof EntityLivingBase)
                ((ItemSlashBlade)blade.getItem()).hitEntity(blade,(EntityLivingBase)curEntity,(EntityLivingBase)thrower);
        }
    }
}

at EntityRapidSlashManager.java:221

if(!blade.isEmpty()){
    ItemSlashBlade itemBlade = (ItemSlashBlade)blade.getItem();
    NBTTagCompound tag = ItemSlashBlade.getItemTagCompound(blade);
    for(Entity curEntity : list){
        curEntity.hurtResistantTime = 0;

        if(!alreadyStuckEntity.contains(curEntity)){
            //UpthrustBlast
            alreadyStuckEntity.add(curEntity);
            if(getThrower() instanceof EntityLivingBase && curEntity instanceof EntityLivingBase)
                UpthrustBlast.setUpthrustBlastSword(blade, (EntityLivingBase)getThrower(), (EntityLivingBase)curEntity);
        }

        if(thrower instanceof EntityPlayer){
            itemBlade.attackTargetEntity(blade, curEntity, (EntityPlayer)thrower, true);
        }
        else{
            DamageSource ds = new EntityDamageSource("mob", this.getThrower());
            curEntity.attackEntityFrom(ds, 10);
            if(!blade.isEmpty() && curEntity instanceof EntityLivingBase)
                itemBlade.hitEntity(blade,(EntityLivingBase)curEntity,(EntityLivingBase)thrower);
        }
    }
}

solution

i pick the casting code out of loop like

if(!blade.isEmpty()){
    NBTTagCompound tag = ItemSlashBlade.getItemTagCompound(blade);
    ItemSlashBlade itemBlade = (ItemSlashBlade)blade.getItem();
    for(Entity curEntity : list){
        //curEntity.hurtResistantTime = 0;

        if(thrower instanceof EntityPlayer){
            itemBlade.attackTargetEntity(blade, curEntity, (EntityPlayer)thrower, true);
        }
        else{
            DamageSource ds = new EntityDamageSource("mob", this.getThrower());
            curEntity.attackEntityFrom(ds, 10);
            if(!blade.isEmpty() && curEntity instanceof EntityLivingBase)
                itemBlade.hitEntity(blade,(EntityLivingBase)curEntity,(EntityLivingBase)thrower);
        }
    }
}

but that's not a good way, maybe try-catch will be better.

dont know why but my gradlew build always failed with symbol not found, so i just recompile these two java into java class and replace the original file, game wont crash, but EntityRapidSlashManager class replacing failed, so i cant use rapid slash...

hope you can find better way to fix this, happy coding

seems fixed in commit 81ef05d
