Greetings again John,
Now I get the idea that you really mean high volume use of the approved API
rather than collisions coming from directly editing another program's memory.
Correct?
I know well about file system locking. I guess the thought never occurred to me that the locking concept might cross over to RAM memory. I knew about operating systems allocating portions of memory to
a specific program. But now come to think of it, I guess it makes sense to incorporate some type of locking when memory is shared. Learn something new every day. Just I never realized such actually
existed.
I am thankful,

Michael,
I get what you are saying but "dynamically unstable at high
volume" isn't even funny anymore. Just from the conversation, I tease out the gist
that whatever is happening doesn't occur
until a flurry of calls starts taking place. I'm saying it's a bug in a path
that causes the offending program(s) to miss a lock on the stack, and then it
becomes a race to update. Then the memory
pointer(s) can be dirty until some other caller tries to reference the
location,...and then, boom! If the stack belongs to Java and *cannot* be
accessed by anyone else, then it's Java's problem to fix.

This sounds like somebody isn't locking/guarding the stack when it is being
updated...probably on the Java side. It might be assuming that no one else is going to
update ITS "proprietary" stack. Wrong.
I thought way back when Java was invented, one of the pros was "no direct memory
access". No?
So is in fact BSF4ooRexx able to directly edit the JVM's memory directly and
bypass the JVM to do so?
I am thankful,
