XWiki fails to start on Tomcat on Windows because critical resource files cannot be loaded

The problem is here https://github.com/xwiki/xwiki-commons/blob/xwiki-commons-17.10.6/xwiki-commons-core/xwiki-commons-environment/xwiki-commons-environment-servlet/src/main/java/org/xwiki/environment/internal/ServletEnvironment.java#L450-L457 . That code adds an extra file separator (backslash) at the end of the path on Windows, leading to:

D:\Win 10 Backup\LUCRU_D\TOMCAT_HOME 11.0.20 - 17.10.6 PostgreSQL\webapps\xwiki\\

Ilie Andriuta Nikita Petrenko you can try setting environment.servlet.allowedRealPaths to your XWiki instance path as a workaround, in xwiki.properties. Something like:

environment.servlet.allowedRealPaths=D:\Win 10 Backup\LUCRU_D\TOMCAT_HOME 11.0.20 - 17.10.6 PostgreSQL\webapps\xwiki\

Replace with your actual path that appears in the logs, making sure to leave a single backslash at the end. Please confirm.

I'm fixing the problem in the meantime, which is easy. The tricky part writing a unit test to cover both Linux and Windows. I have to do a bit of refactoring to be able to "mock" File.separatorChar.

I'll try later this evening, yesterday pasting exact the same as path to permanent directory with

\webapps\xwiki

in the end, didn't resolve it.
