New JPMS enabled releases double the size of jar file #7743
Description
Guava Version
33.4.5-jre
Description
The size of the new JPMS enabled releases double the size of the jar file.
This appears to be due to the fact that every class is duplicated in the multi-release directory META-INF/versions/9, instead of just putting module-info.class in the multi-release directory META-INF/versions/9.
Example
$ du -hs guava-33.4.0-jre.jar
2.9M guava-33.4.0-jre.jar
$ du -hs guava-33.4.5-jre.jar
5.9M guava-33.4.5-jre.jarExpected Behavior
JPMS enabled releases should only grow barely in size, due to the addition of a single new module-info.class.
Actual Behavior
JPMS enabled releases double the size of the jar file.

Appears this is a known issue that will be remedied in 33.4.6.

Thanks, a new issue would have been a better way for me to handle this report.
[edit: Here was the earlier discussion.]

Yes apologies, I searched the issues (both open & closed) and didn't see it reported, so I opened this, not thinking to check the release notes.
