A security property named `jdk.sasl.disabledMechanisms` has been added that can be used to disable SASL mechanisms. Any disabled mechanism will be ignored if it is specified in the `mechanisms` argument of `Sasl.createSaslClient` or the `mechanism` argument of `Sasl.createSaslServer`. The default value for this security property is empty, which means that no mechanisms are disabled out-of-the-box.
