Michael Osipov commented on MWAR-446:
-------------------------------------
I did a bit of analysis. The issue is not in Plexus Archiver because there is a
test which guarantees that ZIP types aren't recompressed:
{noformat}
$ zipinfo dont-recompress-added-zips.zip
Archive: dont-recompress-added-zips.zip
Zip file size: 3368 bytes, number of entries: 5
-rw-r--r-- 2.0 unx 383 b- defN 21-Dec-19 15:02 test.tar.gz
-rw-r--r-- 2.0 unx 157 b- stor 21-Dec-19 15:02 test.zip
-rw-r--r-- 2.0 unx 167 b- stor 21-Dec-19 15:02 namelessrootfolder.jar
-rw-r--r-- 2.0 unx 1070 b- stor 21-Dec-19 15:02 test.jar
-rwxr-xr-x 2.0 unx 1070 b- stor 21-Dec-19 15:02 test.rar
5 files, 2847 bytes uncompressed, 2852 bytes compressed: -0.2%
{noformat}
So the bug must be either in MWAR or MARCHIVER.
