Specification Request
JSR is an abbreviation for JavaspecificationRequests, meaning Java specification proposal. It is a formal request to add a new standardized technical specification to JCP (JavacommunityProcess). Anyone can submit JSR to add new APIs and services to the Java platform. JSR has become an important criterion for Java.

prediction scheme
An instruction transfer predictive confidence assessment scheme proposed by Jacobsen, Rotenberg, Smith, is used in many processors.
Jump program
English full name: Jumpsubroutine
assembly syntax: The operation is (as shown in the outline map):
The program jumps to a given specified address, the valid address is 16-bit absolute address. Before jump, first press the value of the program counter PC and the status register SR into the stack and then jump to the specified address. This instruction has no effect on the CCR (condition code register).
JSR107
October 26, 2012 JSR Specification Committee issued the first early draft of JSR107 (JCACHEAPI). Since the JSR startup, it has been in the past 8 years, so this norm is quite a Java community, but the expert group accelerates this progress due to the more and more demand for caching.
Specifications
JCACHE specification defines a method of cache a Java object to cache, including object creation, sharing access, spooling, invalidation, The consistency of each JVM, etc., can be used to cache data that is most often read in JSP, such as product catalog and price list. Using JCache, most queries will speed up due to cached data (internal tests indicate that the reaction time is approximately 15 times).
Development direction
JSR107 will become part of Javaee7 released in the second quarter of 2013.
