 parameters.copyFail=Failed to create copy of original parameter values for debug logging purposes
 parameters.decodeFail.debug=Character decoding failed. Parameter [{0}] with value [{1}] has been ignored.
 parameters.decodeFail.info=Character decoding failed. Parameter [{0}] with value [{1}] has been ignored. Note that the name and value quoted here may be corrupted due to the failed decoding. Use debug level logging to see the original, non-corrupted values.
+parameters.emptyChunk=Empty parameter chunk ignored
 parameters.invalidChunk=Invalid chunk starting at byte [{0}] and ending at byte [{1}] with a value of [{2}] ignored
 parameters.maxCountFail=More than the maximum number of request parameters (GET plus POST) for a single request ([{0}]) were detected. Any parameters beyond this limit have been ignored. To change this limit, set the maxParameterCount attribute on the Connector.
 parameters.multipleDecodingFail=Character decoding failed. A total of [{0}] failures were detected but only the first was logged. Enable debug level logging for this logger to log all failures.
