> Indexer is OOM prone while indexing large ZIP files
> ---------------------------------------------------
>
> Key: MINDEXER-18
> URL: https://issues.apache.org/jira/browse/MINDEXER-18
> Project: Maven Indexer (Moved to GitHub Issues)
> Issue Type: Improvement
> Affects Versions: 4.0.0
> Reporter: Tamas Cservenak
> Assignee: Tamas Cservenak
> Priority: Major
> Fix For: 4.1.0
>
>
> Indexer is OOM prone while indexing large ZIP files.
> Users reported that indexer tends to OOM while indexing huge (400MB+) WAR and
> other ZIP packed files.
> This is most likely related to JVM NIO bug:
> http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6280693
> Doing ZIP bencharks, searching for alternative ZIP solutions
> https://github.com/cstamas/zip-benchmarks
> More details:
> https://issues.sonatype.org/browse/NEXUS-4100
> Solution: Indexer accesses ZIP files over newly introduced ZipFacade, not
> directly using Java's ZipFile anymore. This facade "decides" what
> implementation should be used. Benchmarking showed Java's ZipFile as the
> fastest one, but is OOM prone.
> Next one by speed is TrueZip, but is slower since it's pure java.
> The facade on ZIP files bigger than 100MB will use TrueZip, and on smaller
> Java's ZIP solution, the threshold is configurable. See NEXUS-4100 for more.
