security-libs/javax.security:

    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.

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 inject external
      replacements for 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-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.
