Why not. Only doubt I'd have is that other usages of the CHM are - I guess - services registry and similar configuration tools, for which write performance is irrelevant: your test measured puts, are there drawbacks on gets or memory usage?

See the original announcement on concurrency-interest by Doug Lea, and the subsequent comments.  The design is up here too.  One of the goals was to drastically reduce memory usage with CHMv8.

Interestingly, Netty uses a backported CHMv8 as well - apparently inspired by our inclusion of it in Infinispan.  ;)
