What is the issue or story related to the change?
High level design: Create custom classes for concurrency which extend logic from classes in java.util.concurrency package but ensure that the MDC and request context is copied from main thread to child threads.
Issue:
To handle concurrency in our services, we make use of java.util.concurrency package. This package contains classes like ExecutorService which handle the thread pool for us and execute Runnable objects in new threads. The implementation is such that thread context is not copied from main thread to child threads, and we lose the MDC context map and other request attributes in the child threads.
