Currently S3Mock uses only a few classes from commons-lang3, and it would probably be worth dropping the dependency for the following reasons:
- Better security. commons-* follows "all features in a single jar" pattern, so a CVE in one of the classes would impact S3Mock
- 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
