BUG: DataXException.asDataXException is not work

as code , if channelLimitedRecordSpeed value is -1 ,
throw DataXException will not work .

-------------------------------------------------------------------------------------------
if (channelLimitedRecordSpeed == null || channelLimitedRecordSpeed <= 0) {
DataXException.asDataXException(FrameworkErrorCode.CONFIG_ERROR,
"在有总tps限速条件下，单个channel的tps值不能为空，也不能为非正数");
}

-------------------------------------------------------------------------------------------

Locate the validation using channelLimitedRecordSpeed and the DataXException.asDataException entry point. Reproduce the case where channelLimitedRecordSpeed is -1 and inspect whether the expected configuration exception is raised. Done means the invalid non-positive value is handled as described by the issue.
