Bumps com.github.chrisvest:stormpot from 2.4 to 4.0.

Release notes

Sourced from com.github.chrisvest:stormpot's releases.

stormpot-4.0

Stormpot 4.0

This is a major release that adds many features and upgrades the minimum Java version requirement to Java 21.

The most notable features are adding support for virtual threads. The background allocator thread is now a virtual thread by default. There is also a new virtual-thread-safe PoolTap implementation available from Pool.getVirtualThreadSafeTap(). The claim methods on the Pool interface still rely on ThreadLocal variables, however, and should be avoided if you plan to access the pool from virtual threads.

The leak detector is now off by default. The implementation of the leak detector has also changed to make it dramatically more scalable with large pool sizes.

Speaking of large pools, it is now possible to create pools with more than 2 billion objects. It's still recommended to keep pools as small as possible, but if you really need a very large number of objects, it's now possible.

Threaded and inline pools can now change their Allocator implementation after they've been created. This is useful if you want to change how objects of the same type are created. The process of switching allocators is asynchronous and eventual, but more controlled than building this functionality into your Allocator implementation itself. Direct pools cannot switch allocators, because all their objects are given up front when the pool is created, and their objects are assumed to not need any significant lifecycle management from the pool.

This is a major release that breaks API/ABI compatibility, but the changes are fairly small, so migrating an existing code base should not be too much trouble. See api-changes.json for the complete list of compatibility changes.
