However, I am encountering several issues with the Java 8 promises aka CompletableFutures.
My issues are :

- Some threads are slow to die (WAITING state is too long)
- Completable.allOf is creating promises in the common ForkNodePool
- I had an exceeded waiting for thread exception
Here are two links that are helping me a lot to solve these problems :
These two articles are well documented and explain in detail how Java/Threads/Java/JVM/Promises and parallel streams work.
