`Object::toString` implementation of a primitive class should return the traditional `ClassName at hash` (rather than listing the field values) not to leak any private and security-sensitive information. A primitive class can override `toString` implementation for their custom string representation.
This reminds me [JDK-8201462](https://bugs.openjdk.java.net/browse/JDK-8201462).
Yes. That is a larger brain dump. My comments
on this thread are hopefully narrower and more
FWIW the current implementation already adds the randomness to
the hash code computation with a constant random 32-bit “salt”
configured at startup but it still carries the `31*x+` pattern which
should be cleaned up.
I didn’t know that; good! Flexibility for the
future my main concern right now.
