It is important for implementations of this method to be aware that there
is no guarantee about what state obj
will be in and the
implementation should be prepared to handle unexpected errors.
Also, an implementation must take in to consideration that instances lost to the garbage collector may never be destroyed.

Overrides the defaults in Utils.DISCONNECTION_SQL_CODES
(plus anything starting with

). If this property is non-null and isFastFailValidation()
is
true
, whenever connections created by this factory generate exceptions with SQL_STATE codes in this list,
they will be marked as "fatally disconnected" and subsequent validations will fail fast (no attempt at isValid or
validation query).
If isFastFailValidation()
is false
setting this property has no effect.
