Almost all the Java requirements I read about talk about specific JVMs
and SR levels. The PTF that go along with that may or may not
be listed. I'm talking about from vendors other than IBM, but
even IBM doc (including when WebSphere didn't distribute its own
JVM) talks about SR levels more than PTFs.
For example, CA-MSM Release V4.1 lists the following requirements:
Your system has IBM Java SDK for z/OS:
■ Java 6.0, build 2.4, at maintenance level SR8 (31-bit only)
■ Java 6.0, build 2.4, at maintenance level SR9 (31-bit or 64-bit)
■ Java 6.0, build 2.6, base build (31-bit or 64-bit)
Note: Java 6.0, build 2.6 is the equivalent of IBM Java 6.0.1.
"java -version" tells me the SR level, so I know what I'm running.
Prior to WAS distributing the JVM with the product, I had to upgrade
Java all the time to specific levels (the WAS team installs that part).
At the time I was doing it often enough that it just didn't seem
worth the extra trouble / space / time and didn't provide me any
extra tracking of the level.
I'm not saying you, Ed or anyone else shouldn't install Java using
SMP/E. I'm just saying I personally don't see a benefit.
