jdk 1.4?

jdk 1.4?

[R Shapiro]

What's the status of jdk1.4 for ppc linux? A project I'm working on is
very eager to switch from 1.3 to 1.4 (all the othe developers are
running intel linux or nt/2000).  Since last Fall I've been running
darwin/osx but it looks like Apple won't have a 1.4 release for quite
some time.  Is ppc linux likely to have a working version soon?

Please cc me directly on any replies.

Thanks -

Or even a version that works with recent mozilla builds would be sweet.
The lizard wants 1.3.1, and we only seem to have 1.3.0_PL1.  Or am I
missing something?

I'd love to be able to use recent mozilla's with java.

Yes, the current Blackdown release. :)

I've got it also (on an iBook FireWire) and it works great. I just wish
that the Blackdown guys would release PPC debs of it too, instead of
just for i386.

lack of JIT hurts though. Have you ever tried the IBM j2SDK for PPC?. It's
noticeably faster on my Powerbook G3. (you can download it from IBM, just
google for it.) Problem is that the IBM jvm has been broken for me since kernel
2.4.16. 2.4.15-pre1 is the last know working kernel for me. On later kernels it
just keeps calling sched_yield() endlessly and burns System CPU time. I'd like
to fire off an email to IBM about the problem, but don't know exactly where to
fire the email off to. I use the blackdown (whose excellent work I appreciate)
release now as well.

Is the blackdown release fast enough for you, or is there something I'm
missing?

Cheers,

I hadn't actually tried the IBM JVM for PPC - the only link I'd seen for
it pointed to some SuSE site. I am, however, running 2.4.17-benh0 on
this iBook, so I guess if you experience is correct, it wouldn't work on
here anyhow. Also, did it come with an OJI Java plugin for use with
Mozilla? (I'd bet not.)

Well, I don't run too much Java stuff, so it's been sort of a non-issue.
I'm sure a JIT for the PPC would speed things up a lot, but the lack of
it hasn't been a real issue for me, for the most part.

Would you mind giving it a shot? (or someone else?) I want to be sure that it's
not a local Glibc issue or such thing. I also haven't tried a recent benh
kernel..

you can download from: http://www6.software.ibm.com/dl/dklx130/dklx130-p

only annoying thing is that you have to register for a password.

Works here, but then I've applied a couple patches:
2.4.18-pre9-benh-o1-xfs-lolat-aa ;)

As you mention sched_yield(), the O(1) scheduler patch could make the
difference?

You can get it from the SuSE FTP server without that.

hmm, I tried the O(1) scheduler with your patch and it still doesn't work.

maybe it's lolat? or benh? I'll try that tonight.

but could you do me a favour? can you try out 2.4.18-rc4 vanilla? and confirm
that it doesn't work? that would eliminate the possiblity that it's a userspace
issue (or rather some kind of kernel-userspace interaction problem)

and you're sure your trying the IBM-jdk right? could be that you have the
blackdown JDK installed as well and it comes first in your PATH or something?
just want to make sure.

thanks in advance.

Why don't you just try Debian instead? ;)

Seriously, I can't test vanilla because my filesystems are all XFS. :)
And it's not that I have too much time, if you know what I mean... I
hope you understand and that your own testing will give some results.

I do have the Blackdown 1.1 and 1.3 JDKs installed as well, but I used
the absolute path to the IBM java executable for testing. Coult it still
have picked up some wrong libraries or something?

I just tried running it on 2.4.18-ben0, with libc6 2.2.5-1 (Debian sid),
and it starts up and seems to run just fine. I did get the binaries from
IBM's site instead of the ones from SuSE's FTP site (the latest bins on
IBM's site are about a month newer). I don't see any JIT in with their
binaries though.

ah ha! that's good to hear. I tried with ben0 and no go, so it means it's
a userspace issue on my box. I'll try debian and see what happens.

thanks for your help.

I had problems with the IBM java also. It worked great the first time
through (running Limewire) but, after that it would always tell me that
it couldn't allocate the needed memory are exit right away.

So I had to switch back to blackdown. I haven't run any actual tests or
anything, but the IBM one seemed faster (probably because it is JIT
enabled), but atleast the blackdown java works.

Re: jdk 1.4?

[Kevin B. Hendricks]

Hi,

To answer you question.  Don't hold your breath.  I simply don't have
the time to work on it and it has not even been released yet.  Once it
gets released I (or some other volunteer) will try and get a version
working.  Note, we do not have hotspot (yet) and the entire jdk 1.4 no
longer support classic threading, so we have to backport and fix it from
jdk 1.3.x.

This will actually take some time that I simply don't have to give.  If
you would like to join Blackdopwn and help out, that would be greatly
appreciated.

I am simply tired of asking for "volunteers" that never work on things
and never help.

If you or someone you know would really like to help, I would greatly
appreciate it.  Please note, the IBM jdk 1.3.X with JIT is out there and
available from SuSE and from IBM.
