Description

Referring to https://netbeans.org/bugzilla/show_bug.cgi?id=253322 , our  project uses ivy to fetch libraries. In our development branch https://github.com/SensorsINI/jaer/tree/ivy-bagreader , 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\oss.sonatype.org

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 https://github.com/SensorsINI/jaer/tree/d6bcf756ca26ae790b73016a61d7188a7b2c3445 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.
