Description

Maven 4 already did this. By introspection, it turns out that 3.9 is also very lightly use commons-lang, while it in fact represents quite noticeable overhead of the ZIP distro size (10% almost). Without commons-lang Maven 3.9.x distro is 9MB only.

Moreover, the presence of commons-lang just introduced some peculiarities:

• confusion over StringUtils (vs Plexus Utils StringUtils)
• skewed param validation: according to commons-lang string "2." is not a valid float, while Float.parseFloat nicely parses it into 2.0 (see MNG-7756)
• PR ended up with same LOC but noticeable smaller ZIP distro, meaning not much was really used out of it
