Oracle installer doesn't work on FC8. The problem is in the new libX11 which is rather buggy when using the new XCB binding mechanism. The error produced by installer is the following:

java: xcb_xlib.c:50: xcb_xlib_unlock: Assertion `c->xlib.lock' failed.

Fiddling with the different versions of Java will not help and neither will the "sed trick" which replaces the codec name in the Athena widget library. The only thing that will help is to replace the libX11 packages

libX11-devel-1.1.3-4.fc8
libX11-1.1.3-4.fc8

with the FC7 versions:
libX11-1.0.3-8.fc7
libX11-devel-1.0.3-8.fc7

Of course, during that operation X11 cannot be active. Bug is well reported on Fedora and affects most of the Java based tools. Netmgr is also affected:

[oracle_at_mladen ~]$ netmgr

java: xcb_xlib.c:50: xcb_xlib_unlock: Assertion `c->xlib.lock' failed. /oracle/product/10.2.0/bin/netmgr: line 161: 4225

Aborted                 $JRE -

Dsun.java2d.font.DisableAlgorithmicStyles=true -mx100m -classpath $CLASSPATH oracle.net.mgr.container.NetApplication oracle.net.mgr.container.NetApplication
[oracle_at_mladen ~]$

In other words, if you are using Java, do not upgrade to FC8:

[mgogala_at_mladen ~]$ uname -a

Linux mladen 2.6.23.1-49.fc8 #1 SMP Thu Nov 8 21:41:26 EST 2007 i686 i686 i386 GNU/Linux
[mgogala_at_mladen ~]$

Scrap Java, use Perl.
