Yesterday I had started to respond to Michaels post, but stopped since I wanted
to read what's available first. Well, given his frustration wiht a semantics
discussion, here comes anyway:
Thank you for asking for input in the first place. (That in itself is kind of a
novelty).

I don't think anyone says that software is perfect. WHat I personally find sad
is that just about every Java programmer doesn't know and doesn't care what the
underlying architecture does and hence is incapable of even analyzing anything.
We currently have a problem where a java application has its main thread
silently terminating, leaving all other threads active but doing nothing. The
application is incapable of determining *why* that thread terminates and is
playing a guessing game. 'It must be too few storage.' Well, even increasing
the storage caused the hang ('this is not a hang').
And did I mention that that address space has region=0M and even gets region=0M
(as in everything available above and below - nothing is used below, the usage
above is negligible).
One thing that rubs me (and probably others) the wrong way is the implication
that a storage leak (or whatever the current mnemonic is) is something to be
tolerated and encouraged by specifying region=0M (your wording "... I am not
sure why customers would want to run Java without REGION=0M, as without it , it
is possible to cause a JVM abend. ..." came across like this to me).
I am with Ed on this: Give me a good unconditional getmain so I can set a slip
trap in abend878/80a/whatever and get good doc. And I have an abending
application that doesn't hang around probably exposing other bugs (like why the
hell doesn't the main thread take all other threads with it as they can't do
anything anyway.)
Regards, Barbara
