Bug Description

The "Illegal file detected" warning message prints a stack trace, but does not indicate which is the offending file without debug logging enabled at the server level.

Expected Behavior

The warning message should include the offending path and filename to aid in locating the offending file. i.e..
[12:31:33 WARN]: Illegal file detected - Invalid characters or extension missing - schematics/runnigndragon (2).schem

Reproduction Steps

1. Place schematic with illegal filename in schematics directory
2. Start Server
3. Check log/console

Anything Else?

I was able to reproduce the error with just the WorldEdit plugin installed.
