[beanutils] ConstructorUtils is unused
Hi All,
In both branch 1.X and master, the class ConstructorUtils is unused
and duplicates APIs in Commons Lang.
I propose to drop it from master, which will be 2.0 when finalized.

I agree; I'll make sure to deprecate it in 1.x and remove it from git
master for 2.0.

+1 for deprecation. Particularly if duplicated in Lang.

Hi Piotr,
Thank you for your digging in the history.
> in
> BeanUtils two years before they were moved to Lang (2008 vs 2010).
That tells me we can complete this move for BU 2.0. Since all
reflection business happens in `java.lang.reflect` and Lang rightly
has much more comprehensive support for `java.lang.reflect`, that's
where the code belongs IMO. This can leave BU to _focus_ on the
`java.beans` aspects.
The fact that `ConstructorUtils` is not even used by BU itself is also
an indication that users who want this functionality can get it from
Lang.

Gary

MethodUtils was added to BeanUtils in 2001

What should be the demarcation between Commons Text, Commons Lang, and
Commons BeanUtils:
- Operations on Java primitive values, arrays, and locale-independent
strings used in configurations or business logic clearly belong in
Lang.
- Handling of text for UI display belongs in Text.
- String interpolation also falls under Text.
- Everything that deals with `java.beans` should be in BeanUtils.
- I’m less certain about reflection logic: BeanUtils feels like
the natural home, although Lang currently also contains duplicates of
it.
I looked at the history and classes like `MethodUtils` appeared in
BeanUtils two years before they were moved to Lang (2008 vs 2010).
