> The {{annotations}} of {{ImmutableMetrics}} uses a {{ConcurrentHashMap}} but that of course loses the insertion order. Convert to a {{synchronizedMap}} that takes a {{LinkedHashMap}} to maintain that order as well as the ability to support concurrent access which is an issue for some graphs. 
> There was some question as to whether or not this change was breaking to the Gryo format or not ,but it appears that it is not. Gryo 1.0 and 3.0 remain as intact as they were on previous releases, though it is worth noting that Gryo 1.0 broke on release on 3.3.0 when it comes to "metrics" serialization so that break is still intact. Therefore you can't use Gryo 1.0 between 3.2.x and 3.3.x/3.4.x. Not sure how that happened exactly.
