Failing to index files with special characters in name

I have created RHDM deployment on OCP and tried to import a git repo into which included a rule file with special char in the name, i.e.:

testüüü.drl

The indexing of such repo fails and the files are not accessible.

This was reproduced in RHDM 7.3 and RHDM 7.6

Issue on RHDM 7.3:

The error has a different stacktrace in RHDM 7.6 - but still has NoSuchFileException 

Example repo here:

The file causing the troubles:

https://github.com/agiertli/sample-repo-rhdm76/tree/master/src/main/resources/com/myspace/sampleproject

 Just change the pom.xml depending on which version you are importing this repo to.
