`ClassUtils.getAbbreviatedName(Class, int)` abbreviates `Class.getName()`, and for an array class the first `.` segment is the JVM array encoding plus the first package name. `"[Ljava"` gets shortened to `"["`, so the `L` marker and the package initial are dropped: `getAbbreviatedName(String[].class, 1)` returns `"[.l.String;"`, and `String[][].class` returns the same string, so different array types abbreviate identically. With a large enough hint the method still returns the full `"[Ljava.lang.String;"`, so only the abbreviated path breaks. The fix keeps the leading `[...[L` prefix and trailing `;` and abbreviates only the element class name against the remaining length budget, giving `"[Lj.l.String;"` and `"[[Lj.l.String;"`. This is the same encoding `getPackageName(String)` and `getShortClassName(String)` already strip in this class. Non-array names and primitive arrays (`"[I"`) are unchanged. The `Class` overload delegates to the `String` one, so one change covers both. `test_getAbbreviatedName_Class_Array` fails before the change (`expected: <[Lj.l.String;> but was: <[.l.String;>`) and passes after. - [x] Read the [contribution guidelines](CONTRIBUTING.md) for this project. - [x] Read the [ASF Generative Tooling Guidance](https://www.apache.org/legal/generative-tooling.html) if you use Artificial Intelligence (AI). - [x] I used AI to create any part of, or all of, this pull request.

This may not always be possible, but it is a best practice. - [x] Write a pull request description that is detailed enough to understand what the pull request does, how, and why. - [x] Each commit in the pull request should have a meaningful subject line and body.
