The fedora.log file does indeed provide greater insight. I traced this problem
to the fedora/data/ directory being owned by root, I imagine caused by my
running fedora-rebuild as root. I have now tried chown'ing the files to the
fedora user and re-running the rebuild as the fedora user. That provided the
same error, as did removing the lock files entirely and restarting tomcat. In
both cases, I get the same FileNotFoundException/Permission Denied error.
Giving the data/ directory to tomcat results in broader-sounding errors, such
as failure to recover the existing database.

Subject: Re: [Fedora-commons-users] [500 Internal Server Error] The Fedora
Server is Not Yet Running
Hi Adam,
Usually this error will be thrown if you try to hit any of Fedora's
APIs while Fedora is still in the process of starting up (it usually
takes a few seconds, rarely over 30). But if you're getting this
error after waiting a minute or two, it looks like Fedora is having
trouble starting. Check your $FEDORA_HOME/server/logs/fedora.log file
(near the end) for hints on why.
