### Search before asking - [X] I had searched in the [issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no similar issues. ### Version in master branch ### What's Wrong? In the fe project, many place use the Pair.java in fe-common module. And I found this case in the code project. <img width="933" alt="image" src="https://github.com/apache/doris/assets/15382560/bd03991e-01e3-4da8-8735-617a1550dd30";> Developers usually input a null value into Pair object, but the Pair.java not support null value with its first and second member correctly. When a Pair object with null value, i would cause the NullPointException by calling its toString method or equals method. (I repeated this case by my unit test) It is very dangerous. And I have fixed it in my forked project. Please assign this issue to me , and then I will pr my commit soon. Thank you very much ### What You Expected? Please assign this issue to me , and then I will pr my commit soon. ### How to Reproduce? Pair<String, Object> firstPair = Pair.of(null, "world"); firstPair.toString(); it will cause NullPointException ### Anything Else? _No response_ ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
