Referring to [] , our  
project uses ivy to fetch libraries. In our development branch 
[] , the index update 
makes a cache that  takes hours to update, grows RAM past 16GB, and has final 
size >41GB in \AppData\Local\NetBeans\Cache\8.2\mavenindex\

Is this expected behavior? During update, the machine (which has 16GB RAM) 
becomes unusable as everything starts churning the paging file.

The exact point this occurs is 
 but we have seen it as soon as we starting using ivy for fetching packages.


The attached log file does not seem to contain this indexing operation but it 
might be helpful.
