--------------------------------------
Summary: Native Memory Leak in Sevenz-DeflateDecoder
Key: COMPRESS-343
URL: https://issues.apache.org/jira/browse/COMPRESS-343
Project: Commons Compress
Issue Type: Bug
Components: Archivers
Affects Versions: 1.10
Reporter: Rene Preissel
The class ...sevenz.Coders.DeflateDecoder does not close (end()) the Deflater
and Inflater. This can lead to native memory issues: see
https://bugs.openjdk.java.net/browse/JDK-8074108.
In our case we create a zip archive with >100000 files. The Java heap is around
300MB (with 2GB max). The native memory is increasing to 8GB and above. Because
the Java heap has no pressure - no GC is triggered, therefore the Deflaters are
not collected and the native memory is not freed.
