    JDK-8295111: `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.

      installations to fail due to missing shared libraries.

security-libs/javax.security:

    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.

infrastructure/build:

    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`.

security-libs/java.security:

    JDK-8316138: Added GlobalSign R46 and E46 Root CA Certificates

      The following root certificates have been added to the cacerts truststore: ``` + GlobalSign  
      + globalsignr46     DN: CN=GlobalSign Root R46, O=GlobalSign nv-sa, C=BE
      
      + GlobalSign   + globalsigne46     DN: CN=GlobalSign Root E46, O=GlobalSign nv-sa, C=BE ```
