Comment 1 Andrew Overholt 2005-11-30 23:02:03 UTC 
I can't reproduce on i386.  Are you using our stuff (gcj/gij/libgcj) or the IBM JVM?
Comment 2 Jock Findlay 2005-12-01 01:50:21 UTC 
I guess I´m using the gcj/gij/libgcj since java is soft linked to
/etc/alternatives/java
which is a soft link to 
/usr/lib/jvm/jre-1.4.2-gcj/bin/java
which is a soft link to 
/usr/bin/gij
(!)

I notice the eclipse website lists the IBM JVM but not the GNU one.  So I´ve
installed the IBM one but obviously it hasn´t replaced the GNU one.  I´m not
overly keen on manually setting all the links and environment variables without
knowing if this is the issue.  Or is changing JVM simpler than that?

This from the error log (found under Help|About|Configuration Details|View Error
Log):

!ENTRY org.eclipse.ui 2 0 2005-11-30 22:07:48.419
!MESSAGE Save Failed
!STACK 0
java.lang.NoClassDefFoundError:
org.eclipse.core.internal.utils.UniversalUniqueIdentifier
   at java.lang.Class.initializeClass() (/usr/lib64/libgcj.so.6.0.0)
...

Can I simply change the JVM in a configuration file?  Which file?
Comment 3 Jock Findlay 2005-12-01 02:17:11 UTC 
Bingo! As root remove /bin/java and then ´ln -s /opt/IBMJava2-amd64-142/bin/java
/bin/java´
Is so easy :-)
Thanks for the help.

Comment 5 Andrew Overholt 2005-12-02 20:45:28 UTC 
The alternatives system is the recommended way of switching between different
JVMs.  This is a good read for working with proprietary JVMs and JPackage:

http://fedoranews.org/mediawiki/index.php/JPackage_Java_for_FC4

Ignore the part about using a 1.5-level JVM.  The procedure can be used for the
IBM JVM as well.  http://jpackage.org might also have some pertinent information.
