The new Java Caching Standard (javax.cache) This post explores the new Java caching standard: javax.cache. How it Fits into the Java Ecosystem This standard is being developed by JSR107, of which the author is co-spec lead. JSR107 is included in Java EE 7, being developed by JSR342. Java EE 7 is due to be finalised at the end of 2012.
