LGTM. Good defensive fix — adds bounds checking (split(":", 2) + length check) and NumberFormatException handling for malformed orderTopicConf entries. The continue approach correctly skips bad entries without breaking the entire route parsing. Applied consistently across both MQClientInstance and MessageQueueSelector.
