Unfortunately since this is a PROD system, we do not have an option to do a enableDebugInfo() and cannot replicate the same in Dev or UAT

We have 3 servers with the same war file deployed and we see that this issue does not happen with all the 3 servers at the same time.

Can you please let us know if Jboss extracts the PD4ML font files from the war to any temp files?

Also why PD4ML is not fetching times font even though it is available and also why it is happening only sometimes and restarting jboss resolves it?
