http://java.sun.com/j2se/1.4.1/install-linux.htmlsiger:
This version of the Java 2 SDK is supported on Intel Pentium platforms running the Linux kernel v 2.2.12 and glibc v2.1.2-11 or later.
...
Most testing of Java 2 SDK 1.4.1 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 2 SDK 1.4.1 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
* Red Hat 7.3 (kernel 2.4.18, glibc 2.2.5)
Redhat 9.0 bør derfor være supporteret. Det magiske ord er "or later".
Sun har bare ikke testet den platform særligt grundigt.
Af indlysende årsager: 9.0 var ikke på gaden da SUN lavede 1.4.1 !
