BACKGROUND: I've spent several hours tried to setup log4j together with Spring MVC on WildFly. The problem was that WildFly has its own logger and it conflicted with my own. Nevertheless I've got it almost working. I had to add jboss-deployment-structure.xml to my WEB-INF folder with this part inside deployment tags:
<exclude-subsystems>
<subsystem name="logging" />
</exclude-subsystems>
now my logs (and more importantly System.out's) appears on the console. However during wildfly startup now I receive an error. It looks like it doesn't break anything in app but I want to get rid of it.

The invalid character Ł is nothing special in polish locale. I use Windows 8.1 and the path is accessible by any program. How can I fix this?
I had to move Wildfly installation folder to another destination which doesn't contain polish characters.
It's a bug in JDK, already reported. For more information look here.
