Just 2 cents - just to be clear on terms "stability" and "reliability" - we
started using them in this thread and I feel like we do not separate them.

I propose, when we are talking about "reliability" we mean:
Capability of Harmony runtime to run given workloads correctly (as it is
defined by J2SE specifications) for certain period of time.
This is interpretation of definition given by IEEE for "reliability".

There is no definition for stability in IEEE software glossary, so I propose
when we are talking about stability we mean stability of runtime / code in
time, i.e. progressing, not regressing.

In these terms I completely agree with the order.
