---------------------------------------------------------------
Hello [~rajugupta]
Thank you for writing up this proposal.
Some notes:
* "deprecating CGLib classes for removal in version 4.0.0." -> 3.0.0.
* "Proceed with ByteBuddy integration in v3.0.0" -> 2.x
I think you're off by 1 ;) as the current version is 2.13.0 with
2.14.0-SNAPSHOT in git master, so:
|*1*|2.x|Add {{@Deprecated}} to CGLib classes; add ByteBuddy implementation|
|*2*|3.0.0|CGLib classes are gone|
Note that we need to stick to a BB version that supports Java 8 in 2.x.
WRT "Add runtime warning when CGLib classes are instantiated", there is no warn
targets as this library doesn't log. Using "Deprecated" annotations is all we
need IMO.
Thank you!

> Key: POOL-417
> URL: https://issues.apache.org/jira/browse/POOL-417
> Project: Commons Pool
> Issue Type: Bug
> Affects Versions: 2.12.0
> Reporter: Gary D. Gregory
> Priority: Major
>
> Provide an alternative to unmaintained Cglib.
> From [https://github.com/cglib/cglib:]
> "{_}*IMPORTANT NOTE: cglib is unmaintained and does not work well (or
> possibly at all?) in newer JDKs, particularly JDK17+. If you need to support
> newer JDKs, we will accept well-tested well-thought-out patches... but you'll
> probably have better luck migrating to something like
> [ByteBuddy|https://bytebuddy.net/]."*{_}
> See also:
> - [Apache Commons BCEL|https://commons.apache.org/proper/commons-bcel/]
> - [ASM|https://asm.ow2.io/]
>
> Since we already have a JRE version of these classes that use {{Proxy}},
> should we deprecate the Cglib classes?
