In case when both pattern-filter and predefined-filter are set in one Object in CLI command for filters of Elytron configurable-sasl-server-factory then it finishes with insufficient failure-description:

/subsystem=elytron/configurable-sasl-server-factory=someFactory:add(sasl-server-factory=global,filters=[{pattern-filter=(.*),predefined-filter=BINDING}])
{
    "outcome" => "failed",
    "failure-description" => "WFLYELY01014: Invalid [filters] definition.",
    "rolled-back" => true
}

This failure-description is not wrong but it is also not helpful. Improve failure-description to say that only one of pattern-filter and predefined-filter can be set in one Object in list of filters.
