> Sometimes it works without complaint. I haven't been able to figure out exactly which conditions tickle this. I had suspicions that it might have to do with whether it was a hot deploy or on the existence of the properties file, but I wasn't able to prove it consistently. It did seem that if there was previously no properties file and I then did a hot deploy with a properties file, then I got the exception. I was able to deploy successfully to 4.2.2.GA. The structure of the WAR is:
