Error Message missing helpful information about failed validation of discriminator schema

Hi,

we are using swagger-request-validator-core version 2.15.1.

It looks like there still is useful information lost when building the report message.

ImmutableMessage#toString prints:

ERROR - [Path '/productOrderItem/0/appointment'] Failed validation of discriminator schema '/components/schemas/Appointment': []

But debuging into SchemaValidator#validate reveals that com.github.fge.jsonschema.core.report.ProcessingMessage contains more helpful information for the same error:

error: failed validation of discriminator schema '/components/schemas/Appointment'
    level: "error"
    schema: "/components/schemas/Appointment"

            }
        }
    ]
