Looking around for Java cache systems, I found that a lot of them claim to be JSR-107 compliant. Now this JSR never went past the review ballot in 2001, and the latest available draft is from 2005.
Among the products that claim compliance, some of them are "serious" ones and I'm surprised that they're happy with a dormant draft specification:
- EHCache
- Google App Engine
- Infinispan (aka JBoss Cache 4.0)
But many of them implement their variant or repackaging of the spec, requiring developers to define their own interfaces to shield the application from these naming variations.
So what happened to this JSR? In these times where memcached is king but memory grids (aka distributed caches) are probably more suited to Java servers, why has it stalled?
