Symptoms
Whether run manually or using the Autoupdate interface, Autoupdate to 4.5.1 fails on the master server. Examination of the updateinstall.log file shows a Java exception after the "Verify md5sum for patch files ... OK" step.

Examination of the dpx.jnlp file in http/ROOT/webapps is likely to show this line near the beginning:
<jnlp spec="1.0+" codebase="$CODEBASE" href="dpx.jnlp">
Resolution
Replace $CODEBASE with the URL for the master server's resolvable name or IP address:
http://master.domain:6122/
Use the appropriate name or IP address for "master server". Keep the quotes that were around $CODEBASE. For example:
<jnlp spec="1.0+" codebase="http://<<master server name or IP address>>:6122/" href="dpx.jnlp">
