LimitedThreadPool is the same with CachedThreadPool?

Hi, Community, 
I found LimitedThreadPool[1] is the same with CachedThreadPool[2],
But in some posts, they are described as a different things, like here[3]:
- LimitedThreadPool is "Creates a thread pool that creates new threads as needed until limits reaches. This thread pool will not shrink
 automatically".
- CachedThreadPool is "This thread pool is self-tuned. Thread will be recycled after idle for one minute, and new thread will be created for
 the upcoming request".


And what's wrong with them?
