I personally think this is a historical legacy issue.
On past JVM platforms, the throughput of some garbage collectors (such as
CMS) was not high, so using Recycler to optimize GC is meaningful.

But on modern JVM,
GC has been greatly optimized.
We need to carefully consider whether this 'optimization'  is still
necessary
