Porting JVM - Minix

Hey all,

I want to port JVM to Minix. Is anybody already working on it?

And which JVM should I port? Suggestions please !

Not that _I_ know of, but it could be

AST has on occasion suggested Kaffe (www.kaffe.org). I don't know the
details of this preference, but it's a clean implementation from scratch,
which will probably make it easier to port than Sun's code.

Hi Siddharth! Quick question...have you ported anything this big
before? Just curious. A JVM is a large piece of code. I agree with
Jens that Kaffe should probably be the JVM of choice. I actually
started working on a port of Kaffe 1.0.7 last year about this time.
Got it to build, but the code output from the java compiler wasn't
correct and, sad to say, I let my port rot in favor of other things.
I am not sure of the state of the code, but it is still sitting on my
dev Minix system. (Uptime 309 days, 3 hours 18 minutes!) There are
probably newer versions out there by now if you want to take on the
port. I haven't seen any new port announcements in awhile, so it
would be good to have some fresh toys to play with. It is getting
close to the holiday season here, so I might even pull off another
port or two before year end! Anyway, on the subject of Kaffe, if you
want to take it on, I say go for it! If you think I can be of
assistance, feel free to e-mail me.

Has anyone considered JNODE for this? I has explored it a long time
ago - its basically a complete OS built in JAVA - ofcourse it has a
JVM written in Java as well!!!...This could potentially be an easier
port!

Exactly why would this be _easier_? From a quick glance, all I can say
about the project is that it looks as if everything is in Java bytecode
except for the nano-kernel and a few architecture-specific classes.
From the site: "After the bootstrapper code, we're running plain java
code.". So, JNode's java interpreter/JIT compiler/whatever is running on
bare hardware, not as a process. JNode's JVM runs on top of this, as pure
Java. What we need for MINIX is a program that runs as a user process and
functions as an intermediary between a Java bytecode program and MINIX. I
could be missing something here, but I don't think JNode will be useful in
the effort to get Minix a working JVM.

Regards,

Jens
