From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.3) Gecko/20030314 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): kernel-2.4.20 How reproducible: Always 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 Additional info:
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.
