Issue Description

Issue	Description
JDK-8328638	Fallback Option For POST-only OCSP Requests JDK 17 introduced a performance improvement that made OCSP clients 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 clients to fallback to POST-only behavior. This unblocks interactions with those OCSP responders through the use of `-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.

Issue Description

Issue	Description
JDK-8326891	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 replace JDK internal native libraries using `LD_LIBRARY_PATH`.
