Opennms webapp startup failure due to unresolved symlinks

I had a new install of OpenNMS on a Fedora 29 system, and saw the following in jetty-server.log when I was trying to startup OpenNMS:

2019-04-14 18:10:59,133 WARN  [Main] o.e.j.w.WebAppContext: Failed startup of context o.e.j.w.WebAppContext@6d39ad25{opennms,/opennms,fil

java.io.FileNotFoundException: /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.201.b09-6.fc29.x86_64/jre/lib/ext/java-atk-wrapper.jar (No such file or directory)

Further investigation through jetty-server.log revealed that all webapps failed to start due to this failure. The root cause of this was two unresolved symlinks in /usr/lib/jvm/java-1.8.0-openjdk/jre/lib/ext/.

I removed the two symlinks, restarted opennms, and the web applications successfully started up. Otherwise, I could have installed the java-atk-wrapper and openjfx packages to provide the jar files the symlinks point to.
