Just read this on Sun's Java site:
Most testing of Java RE for Linux in the English-locale has been conducted on Red Hat 7.2, with kernel patch 2.4.9-31. Most testing in non-English locales has been conducted on Red Hat 7.1. However, Java RE has undergone limited testing on these other Linux operating systems:* Caldera Open Linux 3.1 (kernel 2.4.2, glibc 2.2.1)
* Turbo Linux 7.0 (kernel 2.2.18, glivc 2.1.x)
* SuSE Linux 7.1 (kernel 2.4, glibc 2.2.14)
* Turbo Linux for Simplified Chinese locale
Umm, Sun, RH7.2 is so ridiculously outdated that you should be taken out back and shot. The current incarnation, Fedora Core, is on version 4 (as of Monday) which means you are testing on a release that is 6 (RH8, RH9 and the 4 FCs) versions behind the times. This version has been unsupported by Red Hat for a few years. Please update your test environment to something modern. Thankyouverymuch.
