Environment:
SLES10SP1 (minimal install)
Additional packages:
java-1_5_0-ibm-devel-1.5.0_sr3-13.10 (and all deps)
mysql (and all deps)
JBoss 4.0.5.GA

Problem:

I've completed the installation up to the point where I need to run
configupdate.sh. When I do I get the following exception:

-- snip --
com.sssw.fw.util.crypto.MasterKeyException: Master key is corrupted in
configuration file.
.....
Caused by: java.security.InvalidKeyException: Illegal key size
-- snip --

I've confirmed that the contents of the key in
/opt/novell/idm/master-key.txt and
/opt/jboss/server/IDM/conf/sys-configuration-xmldata.xml are the same.

Does anyone have any ideas what may be causing this?
