[1.12] java.lang.ClassCastException: java.lang.Boolean cannot be cast to java.lang.Integer

[Purplicious_Cow]

Hey Team Forge -

 

I have a question, very similar to this thread at the very bottom of this post answered back in July '17. I have seen crashes like the below reported on Animania reported since its launch 9 months ago. It does appear to be "heap pollution", as you suspect, as it only occurs in multi-mod environments (where at least one of the mods adds other custom entities) and in a server environment. There is nothing in my code that would or could even change the stored value from an Integer to a Boolean (that's just weird). Based on all evidence it is externally created, and can happen to any animal and any parameter.

 

Example crash: https://github.com/capnkirok/animania/files/1652984/crash-2018-01-22_12.33.17-client.txt

 

However, I have no idea of identifying which mods are causing the problem. I saw another discussion about this elsewhere where Vazkii chimed in and said the only real way avoid the issue altogether is to move from Data Parameters to Capabilities. 

 

Any suggestions here? I would love to be able to error trap it, but I can't even do that (unless you know a way). Or would you recommend moving to Capabilities?

 

Thx,

Purp

Thanks, diesieben07,

 

But I'm not going to do that for modpackers with hundreds of mods. So, to be clear...

 

• So you don't recommend using capabilities?
• Also.. based on your response... what if I am extending some vanilla entities (for instance EntityCow) ... could that be a source of conflict if other mods do the same and add their parameters to an extended class?

Do it by binary halves:

 

PIck half of the mods (alphabetically works). Doesn't need to be an exact half. Just make sure that Animania stays in each time.

Remove those mods.

If the problem persists, remove half of what remains.

If the problem goes away, put half of the most recently removed mods back.

Repeat until adding/removing a single mod causes the problem.

 

This should take no more than 7 iterations for ~100 mods.

Yes, I do. But they have a completely different purpose than DataParameters. "You should not use a screwdriver to put a nail into the wall." - "So I should never use screwdrivers?".

No, no, I meant, do you think it's a bad idea to use Capabilities to do the same thing that DataParameters are doing.

Yes. You must only add DataParameters for entities that you create. Otherwise you must implement the data synchronization manually.

@diesiben07, thanks for the response. Ok, so it sounds like I have to implement the data synchronization manually. For some reason, I though the entity automatically did this (writeToNBT). How would you recommend I sync manually, using network packets?

 

Finally, I'm going to include one of my entity base classes for the Ferret, which has crashed with this error, just in case I'm doing something really dumb with this and I don't know it (distinct possibility). This one extends EntityTameable (which has its own parameters, of course)

Capabilities are not automatically synced, as there may be capabilities that the client does not need to know about.

FYI, I went with Lycanite's solution, which is to use try/catch on all attempts to access the data. On failure, it reverts to a default state. It's not ideal, but it prevents crashing in the case there is a conflict. Example:

 

public float getFloatFromDataManager(DataParameter<Float> key) {
		try {
			return this.getDataManager().get(key);
		}
		catch (Exception e) {
			return 0;
		}
	}

You're in the wrong place. We don't fix problems with using mods, we fix problems with making mods.
