Subject Re: Different behavior on startup from version 6 and 7 to version 8, 8.5 and 9
Date Mon, 27 Feb 2017 10:02:24 GMT
*UPDATE: *Making further tests while I was waiting for some answers I found
out that if I explode the war by myself (unziping the war file into the
webapps folder) I still experience the problem. So I think we can rule out
the assumption that the problem happens while the application is still
exploding the war file and that the file size affects it.

Another info that might be useful:

- I am creating this folder using;
- I am trying to check if this folder exist using

Best regards,
