> The current ThreadContext map and stack implementations allocate temporary objects. This ticket is to investigate and track the work for alternative implementations that are garbage-free.
> Both DefaultThreadContextMap and DefaultThreadContextStack are copy-on-write data structures: each modification replaces the ThreadLocal object with a modified copy. The advantage of this approach is that there is no need to make a copy for each LogEvent.
> Also, DefaultThreadContextMap uses a JDK map, the JDK collections tend to allocate a lot of temporary objects.
