It would be useful if you could say which JDK releases you see this. As 
Jai linked to, the JDK is temporarily working around an issue with libz 
on macOS aarch64 since JDK 19 by using bundling a build of in-tree code. 
So it would be interesting to know if these reports include JDK 19 or 
are only older releases.
