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

             Summary: Drop commons-lang3 dependency
                 Key: CALCITE-7259
                 URL: https://issues.apache.org/jira/browse/CALCITE-7259
             Project: Calcite
          Issue Type: Improvement
    Affects Versions: 1.40.0
            Reporter: Vladimir Sitnikov


Currently Calcite uses only a few classes from commons-lang3, and it would probably be worth dropping the dependency for the following reasons:
1) Better security. commons-* follows "all features in a single jar" pattern, so a CVE in one of the classes would impact Calcite
2) Fewer bytes to ship with binary distribution for the end-users: `commons-lang3` is ~690K

I have raised a suggestion to make commons-lang3 modular and extract modules like commons-stringutils, commons-arrayutils, however, {{Commons}} team does not seem to like the idea.
Commons PMC members often suggest that users should clone the code or shade commons-lang, see https://lists.apache.org/thread/xzdhv57o9rnxtzn5fqbtkzj0hdkbm339

So I wonder what do you think of dropping commons-lang3 and replacing it with core Java?
