`jpackage` Apps May Fail to Build on Debian Linux Distros Due to Missing Shared Libraries


There is an issue on Debian Linux distros where jpackage could not always build an accurate list of required packages from shared libraries with symbolic links in their paths, causing installations to fail due to missing shared libraries.

Issue Description
JDK-8328638

Fallback Option For POST-only OCSP Requests


JDK 17 introduced the performance improvement that made OCSP client unconditionally use GET requests for small requests, while doing POST requests for everything else. This is explicitly allowed and recommended by RFC 5019 and RFC 6960. However, we have seen OCSP responders that, despite RFC requirements, are not working well with GET requests.

This release introduces a new JDK system property to allow fallback to POST-only behavior to unblock interaction with those OCSP responders: -Dcom.sun.security.ocsp.useget={false,true}. This amends the original change that introduced GET OCSP requests (JDK-8179503). The default behavior is not changed; the option defaults to true. Set the option to false to disable GET OCSP requests. Any value other than false (case-insensitive) defaults to true.

This option is non-standard, and might go away once problematic OCSP responders get upgraded.

Native Executables and Libraries on Linux Use `RPATH` Instead of `RUNPATH`


Native executables and libraries on Linux have switched to using RPATH instead of RUNPATH in this release.

JDK native executables and libraries use embedded runtime search paths to locate other internal JDK native libraries. On Linux these can be defined as either RPATH or RUNPATH. The main difference is that the dynamic linker considers RPATH before the LD_LIBRARY_PATH environment variable, while RUNPATH is only considered after LD_LIBRARY_PATH.

By making the change to using RPATH, it is no longer possible to inject external replacements for JDK internal native libraries using LD_LIBRARY_PATH.
