Description of problem:
With a custom kernel 2.4.20 which I recompiled with gcc-3.2.2-5 from
RH9, applets I wrote (and recompiled with javac from Sun JDK1.4.1_02)
won't run properly. It's not a NPTL thread isuue, as they do run
properly with the 2.4.20-8smp kernel installed with rh9. They also ran with rh7.3
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.upgrade from redhat 7.3 to redhat 9
2.boot with custom kernel 2.4.20smp-perso
3.launch applet with threads (with mozilla, appletviewer or binfmt-misc).
Actual Results: My applet uses a volatile Thread supposed to draw a blinking
image,actally a text. The text doesn't show with my custom kernel, as it did
before, and still does with kernel-2.4.20-8smp coming with redhat9
Expected Results: Same as before or with your kernel
so you use an app that we don't ship and find it doesn't get along with a kernel
we don't ship. Could you explain how this is a bug for me ??? ;)
It's definitely *not* a bug for you. But I was used, since 1998, and RedHat 5.0,
to helpful corporates at redhat, even when I didn't pay anything (nevertheless I
paid for RH 5.0,5.1,6.0,6.1,6.2, and rhn 15 days ago). I first asked on redhat's
newsgroups, and got no answers. Even if you don't feel concerned about it all,
just forward yo your boss(es). Thanks
Sounds like a problem that should be reported to Sun, so they can fix
their Java. Definitely not a Red Hat bug if you're using a kernel we
don't ship with software we don't ship.
GuruLabs gave me the answer: Java Plugin from Sun does'nt work with mozilla 1.3.
You have to switch back to mozilla 1.2.1 (and so you can use galeon!), or switch
to Blackdown java. I feel you could have tried to find this answer for me.
Bugzilla is not a support mechanism, see http://www.redhat.com/support for that.
I'm a kernel engineer, and I'm more than happy to receive defect reports about
the kernel, but I don't know nor work on mozilla, which you didn't even mention
you had changed to a non-RHL version.
Indeed, I must second Arjan here. Many people file "help" requests in bugzilla,
perhaps because they don't know where else to turn, but bugzilla very much
is not a technical support forum of any kind.
While it is true that any of us could have dropped what we are doing as
work tasks and ran around the internet randomly looking for a solution to your
problem, that is not what we are paid to do. We are paid as developers to
fix bugs in the individual software components we maintain, and to do development
and various other things. Not for technical support however.
If anyone requires any form of technical support, Red Hat provides both
mailing lists for community based tech support forums, and also corporate
tech support contracts.
Sorry. I did'nt even think mozilla-1.3 was the cause, as it worked before with
rh7.3, and with RHL kernel 2.4.20-9smp. I was only hoping you could tell me
which related kernel config option was set inyour kernel.
