are

any work on them.

Ah. OK.

No, rather I was just wondering if a JavaOS optimized for z/VM might be

To my knowledge, there are no software charges for zAAPs or any other
speciality engine other than the IFL.
So two IFLs, the software is charged for two engines.
One IFL and one zAAP, the software charge is for one engine.

Except that the zAAP would only be relevant if you
z/VM 4.4.0 was the last release where JAVA was available for VM. We
actually got to a roughly JDK 1.1.6 level before discontinuing support.
If you still have a z/VM 4.4.0 system and you want to attempt moving the
JAVA code from there to a more recent z/VM 5.x system, the code should

Dear all,
Does a JAVA VM for z/VM (CMS) exists? Only asking for curiosity to play a
round.
Thank you very much in advance.
Best regards,

There was (is?) a Java for VM. It was stabilized at the Java 1.4 level. I don't know
if it will run on current z/VM
Hi, Florian.
At one time IBM did offer a Java VM running on CMS, but that has long since been dropped
from the product. I seem to recall that the last version IBM offered was at the Java 1.4
level or thereabouts, so by now it would be completely outdated. A search of the IBM VM
web site might

1.1.4 for OpenVM. Bye CMS. Hello Linux and Java 6. :)

There was one in the distant past. IBM discontinued it at about Java
1.2.
You could probably still get it via RPQ, but it's not very useful at
this point.

Did it ever get to 1.4? I thought it was 1.1.4.

You're probably right, 1.4 sounded way optimistic... :)
