Right, my thinking was to use the same path usj/jzlib.jar to signal the classpath conflict. Otherwise, we can install it to usj/jruby-jzlib.jar and not make the packages conflict, but I'm not sure what would happen if both were installed at the same time, at the JVM-level.

If both jars are loaded in the classpath the JVM will randomly resolve the classes from the 2 files, that may lead to runtime errors if the two implementations are not binary compatible.


There are some (small) code changes as well, here is a pkgdiff report: https://paste.lib3.net/lavamind/2023-10-24-gBV6KdXXUJ4R0DlxXjjnjz0RmA9OCJ6goNYKux5c03M/changes_report.html

Looking at the changes :

* DeflaterOutputStream.java: exception message changed
* GZIPHeader.java: private 'time' variable removed
* GZIPInputStream.java: getModifiedTime method added (typo fix)
* Inflate.java: call a setter instead of setting the variable directly
* ZStream.java: comment change

The only notable change is the addition of getModifiedTime(), we can add it to the existing package.


In addition, I believe there may be more substantive changes in the future since there are zlib-related bugs reported against JRuby which may lead to further changes in jruby-jzlib, see https://github.com/jruby/jruby/issues/6613

Good point. If the code diverges significantly an independent package is perfectly justified then.

Alright, thanks for the analysis! I'll patch GZIPInputStream.java in the existing jzlib package to add getModifiedTime(), and I'll keep an eye on jruby-jzlib and upload it if/when it diverges more from jzlib.
