I have exactly the same problem.
The most surprising thing is that I've been able to install it in graphical mode on a Linux Suse SLES 11.1 without problem.
On a AIX 18.104.22.168 server, without access to a graphical x-windows console, ie installing in text mode, I have the same failure.
I wonder if it is a problem of :
- OS, are there some supported operating systems listed by redhat?
- JVM, are there some "officialy adviced" JVM ?
Biut I have a "IBM J9 VM" JRE 1.6.0 compliant, on both servers
- Bug in the text mode installer ?
