Troy,

Success!!!!!!

Eclipse now starts up correctly with the java-1.6.0-openjdk installed. The
only snag I ran is if the java-1.6.0-sun-compat is installed first, it creates
the symbolic link /usr/bin/java pointing to /usr/java/default/bin/java. In
order to use the java-1.6.0-openjdk this needs to point to /etc/alternatives/java.
(It's possible that this link is being put in place by the jdk RPM.)

Pointing /usr/bin/java to /etc/alternatives/java still allows the
java-1.6.0-sun-compat java to work properly. When the java-1.6.0-openjdk is
installed, it is automatically selected at the "best" version and Eclipse is
happy.

Thanks for your help in fixing this problem.
