First the JAVA web page will help: http://www-03.ibm.com/systems/z/os/zos/tools/java/ drilling down on that web page for the appropriate version will lead you to additional help.
On the page look for and click on the link "IBM 31-bit SDK for z/OS" " Java Technology Edition, V6.0.0 IBM 31-bit SDK for z/OS Build Level: July 06, 2014 - SDK6 SR16 FP1 (PTF UI19838 / APARs PI21725 and PI21726)" Then "Product History" will take you to where you click on the "Service Summary" link, this will give you the SR#'s and FP#'s going back. I agree with Mark Jacobs, the Build is just a WAG, I think it comes from what was done by Oracle. At least they both are the 31-bit versions of JAVA.

I have 2 different copies of Java 1.6.0 and am trying to decipher which is the more current. I've been under the assumption that the SRmFPn gave the maintenance level, and that the higher the numbers, the more current the fix pack. However I have the following 2 levels of Java and don't know which is newer: # ./java -version java version "1.6.0" Java(TM) SE Runtime Environment (build pmz3160_26sr5fp2-20130423_01(SR5 FP2)) IBM J9 VM (build 2.6, JRE 1.6.0 z/OS s390-31 20130419_145740 (JIT enabled, AOT enabled) # ./java -version java version "1.6.0" Java(TM) SE Runtime Environment (build pmz3160sr13fp2-20130424_01(SR13 FP2)) IBM J9 VM (build 2.4, JRE 1.6.0 IBM J9 2.4 z/OS s390-31 jvmmz3160sr13fp2-20130423_146146 (JIT enabled, AOT enabled) Based on the SR5 FP2 on the first one versus the SR13 FP2 on the second one, I would take the second one as being newer maintenance level, but the first says it is build 2.6 and the second is 2.4. Can somebody explain the differences please? If explaining the differences consists of pointing me to a manual that does the explanation that would be fine as well, but I couldn't find anything.
