      public final class LongRangeFieldValidator
      extends RangeValidatorSupport<Long>

  Field Validator that checks if the long specified is within a certain range.
  - fieldName - The field name this validator is validating. Required if using Plain-Validator Syntax otherwise not required
  - min - the minimum value (if none is specified, it will not be checked)
  - max - the maximum value (if none is specified, it will not be checked)
  - parse - if set to true, minExpression and maxExpression will be evaluated to find min/max
  - minExpression - expression to calculate the minimum value (if none is specified, it will not be checked)
  - maxExpression - expression to calculate the maximum value (if none is specified, it will not be checked)
  You can either use the min / max value or minExpression / maxExpression (when parse is set to true) - using expression can be slightly slower, see the example below. Do not use ${minExpression} and ${maxExpression} as an expression as this will turn into infinitive loop!
