It's probably not a bug but I don't know the source of this message and I don't know what was happening to the server when it appeared. Does anyone know how to solve?

Now it has! It happened only once but anyway it's important to know the reason to be able to catalog this information.
I didn't do a deeper search because of the time but I took a quick look at the oracle website and found this information: https://community.oracle.com/tech/developers/discussion/1529911/badpaddingexception-message-is-larger-than-modulus

I think I figured out the reason for this message: the player was using a custom interface and a modified system, it allows the password to be up to 68 characters long.
I'm guessing that this is it.... that was what seemed most acceptable to me.
