---------------------------------------
Summary: Avoiding Java native peer objects that override finalize()
Key: COMPRESS-473
URL: https://issues.apache.org/jira/browse/COMPRESS-473
Project: Commons Compress
Issue Type: Improvement
Reporter: Roman Leventov
Objects that override finalize() are very bad for GC. The infrastructure
library such as Commons Compress is probably the right place to do the hard
work of eliminating dependencies on such objects. Instead, PhantomReference
registered in a Queue, or sun.misc.Cleaner (or java.lang.ref.Cleaner) should be
used.
In particular:
java.util.zip.Deflater/Inflater/ZipOutputStream/ZipInputStream/GZipOutputStream/GZipInputStream
should not be used.
The issue for Zstd created in a downstream library:
[https://github.com/luben/zstd-jni/issues/83]
Some other downstream dependencies could be affected too.
Commons Compress's own ZipFile and BZip2CompressorOutputStream classes should
not override finalize() too.
