Description

Hello,

I was trying to programmatically load a XML config file from the temporary data directory of a MacOS X system. The temp path consists of serveral '+' characters like MacOS automatically generates this path so we have to take it this way. Even I would agree that it is not nice to have '+' chars in a path name.

When I tried to load the XML config the framework permanently loaded the DefaultConfig and not the desired XML configuration.
By stepping through the debugger I figured out that this was caused by the method fileFromURI() in org.apache.logging.log4j.core.helpers.FileUtils.java .
The misbehaviour was basically caused by the call of URL.decode() which converts '+' to ' ' (space) of a given String.
Now I self-compiled the whole framework without the call of URL.decode() and the XML configuration loaded properly.
I can not see why this call is necessary in this method so in my opinion this should be removed.

Kind regards
