RELEASE NOTES:

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-8281658: New Security Category for `-XshowSettings` Launcher Option

      The `-XshowSettings` launcher has a new `security` category. Settings from security
      properties, security providers, and TLS related settings are displayed with this option. A
      security sub-category can be passed as an argument to the security category option. See the
      output from `java -X`:
      
      ```    -XshowSettings:security        show all security settings and continue   
      -XshowSettings:security:*sub-category*        show settings for the specified security
      sub-category and continue. Possible *sub-category* arguments for this option include:       
      all: show all security settings and continue        properties: show security properties and
      continue        providers: show static security provider settings and continue        tls:
      show TLS related security settings and continue ```
      
      Third party security provider details will be reported if they are included in the application
      class path or module path and such providers are configured in the `java.security` file.

    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 ```

    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.

    JDK-8295111: `jpackage` May Produce an Inaccurate List of Required Packages on Debian Linux Distros

      Fixed 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.

    JDK-8314573: G1: More Deterministic Heap Resize at Remark 

      During the Remark pause G1 adjusts the Java heap size to keep a minimum and maximum amount of
      free regions as set via the `-XX:MinHeapFreeRatio` and `-XX:MaxHeapFreeRatio` options.
      
      Before this change, G1 considered Eden regions as occupied (full) for this calculation. This
      makes heap sizing very dependent on current Eden occupancy, although after the next garbage
      collection these regions will be empty. With this change, Eden regions are considered as empty
      (free) for matters of Java heap sizing. This new policy also aligns Java heap sizing to full
      GC heap sizing.
      
      The effect is that G1 now expands the Java heap less aggressively and more deterministically,
      with corresponding memory savings but potentially executing more garbage collections. 

    JDK-8315503: G1: Balance Code Root Scan Phase During Garbage Collection

      The Code Root Scan Phase during garbage collection finds references to Java objects in
      compiled code. To speed up this process, G1 maintains a remembered set for compiled code that
      contains references into the Java heap. That is, every region contains a set of compiled code
      that contains references into it.
      
      Assuming that such references are few, previous code used a single thread per region to
      iterate over a particular region's references, which poses a scalability bottleneck if the
      distribution of these references is very unbalanced.
      
      G1 now distributes this code root scan work across multiple threads within regions, removing
      this bottleneck.
