Description (partial)

The Network Registrar installation is successful, but attempting to connect into the web UI results in the browser session "hanging".

Review the most recent logs/catalina.<I>yyyy</I>-<I>mm</I>-<I>dd</I>. If this file contains the following lines, this is the issue.

SEVERE: A child container failed during start
java.util.concurrent.ExecutionException: org.apache.catalina.LifecycleException: Failed to start component 
Caused by: org.apache.tomcat.util.bcel.classfile.ClassFormatException: Invalid byte tag in constant pool: 18

If Java 1.8 or later versions of 1.7 (1.7.55 and later are suspected) have been installed, the tomcat (catalina) web services may fail to start.
