Description

Looks like CorePropertiesLocator was switched over to use the new java.nio stuff... and the simplified version of the walkFileTree method does NOT follow symlinks by default. This is a critical feature that needs to be supported for anyone who has their solr core(s) defined elsewhere, and set up their solr home directory to point to those cores via symlinks. It's important to realize that this is the behavior that has always existed pre-5.4.0 by the nature of using the java.io package to listFiles.

I'm attaching a PATCH with the appropriate fix.
