Subject: RE: Attn 7.1 users who plan on staying there for an indefinite time
Rob,
At V7R1, we are still using JDK6, as a default, three 3rd party apps.
We do NOT have a *SYS Java_Home environment variable, so I assuming JDK 6 is the V7R1 default, is this correct?
Or, every Java app we are running has the JDK hardcoded, somewhere, somehow.
We have one in-house app using JDK8, set by a *JOB Java_Home environment variable.
I found some notes from 2013, we added a *SYS Java_Home, caused our credit card app to fail on startup. (Curbstone C2)
Thus, the Java_Home was removed.
For V7R2 and V7R3, what would be the default JDK if no *SYS Java_Home envirnament variable is set.
Reading the tech doc below, from my understanding, you should have Java_Home variable, either *SYS or *JOB.
Without it, how does the system know which JDK to use?
Anyone out there on V7R2 or V7R3 and no Java_Home, which JDK is being used?
" Beginning in IBM i 7.1, the IBM Technology for Java is the only available JVM, and it requires the environment variable JAVA_HOME to be specified to determine which JDK to use. This is important to note because a Java application that relied on java.version to set the version will potentially not use the same Java JDK version as in previous releases."

I recommend that 7.1 users download JDK 7 and JDK 8 from ESS (before EOS of 7.1 on April 30, 2018) and get those installed on to their IBM i.
IBM will drop support for JDK 6 after December 31, 2017.
IBM i 7.3 does not support JDK 6 at all.
Therefore, your vendors may come out with a version which may require that you upgrade your JDK.
These versions of JDK are not on your distribution media and must be ordered directly from ESS (aka Entitled Systems Support)
