This was among the original message that lead to this original subject line.

Hmm. Given that file name, it looks like the OSCAR WAR file ships with testing data inside of it. Tomcat tries to cache items which is why you are getting this warning.

For now, I think you can safely ignore these warnings. They will only (negatively) affect the performance of your Tomcat/OSCAR deployment, but they shouldn't break anything.

The maximum cache size is set by default to 10MiB. If you have more RAM, feel free to increase that number as high as you feel is appropriate.
