security-libs/javax.net.ssl:

    JDK-8163326: Updated the Default Enabled Cipher Suites Preference

      The preference of the default enabled cipher suites has been changed. The compatibility impact
      should be minimal. If needed, applications can customize the enabled cipher suites and the
      preference. For more details, refer to the SunJSSE provider documentation and the JSSE
      Reference Guide documentation.

core-libs/java.net:

    JDK-8161016: Modified HttpURLConnection behavior when no suitable proxy is found

      The behavior of HttpURLConnection when using a ProxySelector has been modified with this JDK
      release. HttpURLConnection used to fall back to a DIRECT connection attempt if the configured
      proxy(s) failed to make a connection. This release introduces a change whereby no DIRECT
      connection will be attempted in such a scenario. Instead, the HttpURLConnection.connect()
      method will fail and throw an IOException which occurred from the last proxy tested. 

    JDK-8161016: Modified HttpURLConnection Behavior When a Suitable Proxy Is Not Found

      The behavior of `HttpURLConnection` when using `ProxySelector` has been modified in this JDK
      release. `HttpURLConnection` used to fall back to a direct connection attempt if the
      configured proxy(s) failed to make a connection. Beginning with this release, the default
      behavior has been changed to no longer use a direct connection when the first proxy connection
      attempt fails.
      
      A new system property, `sun.net.http.fallbackToDirect`, can be set to a value of "true" should
      an application need to fall back to the old behavior (fall back to a direct connection when
      the first proxy connection attempt fails).

    JDK-8269851: OperatingSystemMXBean.getProcessCpuLoad Is Now Container Aware

      For JVMs running in a container, `OperatingSystemMXBean.getProcessCpuLoad` now considers only
      the CPU resources available to the container when calculating CPU load. Prior to this change,
      the calculation included all CPUs on a host. After this change, management agents may report
      higher CPU usage by JVMs in containers that are constrained to a limited set of CPUs.
