Question:

How can you tell the difference between Java Release 7.0 and 7.1  -version  information when both show "JRE 1.7.0"?

Answer:

Java release 7.0 and 7.1  -version  information can be confusing.  Both will show "JRE 1.7.0". To tell the difference between Java release 7.0 and 7.1 you will need to look at the build level.  Java release 7.0 will show build 2.6 while Java release 7.1 will show build 2.7.  Examples are below: 

 

Java 7.0

java version "1.7.0"
Java(TM) SE Runtime Environment (build pxa6470sr9fp40-20160422_01(SR9 FP40))
