concurrentlinkedhashmap 1.2 vs 1.4
Hi,
I noticed Solr is using concurrentlinkedhashmap v1.2 which is for Java
5, according to notes at
https://code.google.com/p/concurrentlinkedhashmap/ version 1.4 has
performance improvements compared to v1.2, isn't Solr 4.x designed
against Java 6+? If so, wouldn't it benefit from v1.4?
Regards,
Guido.

Done, created under SolrCloud component, couldn't find a more
appropriate like Server - Java or something, hope it has all the info
needed, I could contribute to it sometime next week, waiting for new PC
parts from Amazon to have a proper after work dev environment.
Regards,
Guido.

I think it would need Guava v16.0.1 to benefit from the ported code.

As notes also stated at concurrentlinkedhashmap v1.4, the performance
changes were ported to Guava (don't know to what version to be honest),
so, wouldn't be better to use MapMaker builder?

Guido.
