Note the %20 in the file path.

Workaround:
==========

Do not use the indexing tools within a path that contains spaces

To Fix:
=====

IndexingConfig MUST URL decode the URL for resource loaded form the Classpath

* url loading in IndexingConfig#loadViaClasspath
* fix required in IndexingConfig#getConfigClasspathRootFolder
