dsuper7: Had a giant awful project I just loaded and was rebuilding the javascript library when it brought this puppy to its kneeeeeees. 

Steps to reproduce: 
- Obtain disorganized project with thousands of files littered with syntax errors. 
- Download all of those files by adding the ftp server that hosts them as a remote host for a PHP Project in Netbeans 
- Allow netbeans to scan the entire project. *NOTE: I have phpmd phpcs installed as well. 
- Once the scanning is complete click the Javascript LIbrary rebuild link via the project properties dialouge. 

**Observe while struggling to gather all of the millions of javascript libraries it crashes and burns.
