core-libs/java.util.jar:

    JDK-8189789: Decode error with Tomcat version 7.x

      The zlib version shipped in the 8u151, 7u161 JDK releases was updated to zlib v1.2.11. The
      deflate functionality in this version causes a compatibility issue with Tomcat v7.x. Server
      responses can appear as corrupt or can fail to be decoded. The issue is seen if Tomcat is
      using compression (e.g. compression="on" in server.xml). This issue is being fixed via
      JDK-8189789 [https://bugs.openjdk.java.net/browse/JDK-8189789].
      
      Users could disable the compression mode on their Tomcat servers as a workaround. Tomcat
      versions 8.x and later don't appear to be affected.

    JDK-8148421: TLS Session Hash and Extended Master Secret Extension Support

      Support has been added for the TLS session hash and extended master secret extension (RFC
      7627) in JDK JSSE provider.  Note that in general, a server certificate change is restricted
      if endpoint identification is not enabled and the previous handshake is a session-resumption
      abbreviated initial handshake, unless the identities represented by both certificates can be
      regarded as the same.  However, if the extension is enabled or negotiated, the server
      certificate changing restriction is not necessary and will be discarded accordingly.  In case
      of compatibility issues, an application may disable negotiation of this extension by setting
      the System Property `jdk.tls.useExtendedMasterSecret` to `false` in the JDK. By setting the
      System Property `jdk.tls.allowLegacyResumption` to `false`, an application can reject
      abbreviated handshaking when the session hash and extended master secret extension are not
      negotiated.  By setting the System Property `jdk.tls.allowLegacyMasterSecret` to `false`, an
      application can reject connections that do not support the session hash and extended master
      secret extension.

    JDK-8163237:   Disable exportable cipher suites

      To improve the strength of SSL/TLS connections, exportable cipher suites have been disabled in
      SSL/TLS connections in the JDK by the `jdk.tls.disabledAlgorithms` Security Property.

    JDK-8187577: JVM Crash during G1 GC

      A klass that has been considered unreachable by the concurrent marking of G1, can be looked up
      in the `ClassLoaderData/SystemDictionary`, and its `_java_mirror` or `_class_loader` fields
      can be stored in a root or any other reachable object making it alive again. Whenever a klass
      is resurrected in this manner, the SATB part of G1 needs to be notified about this, otherwise,
      the concurrent marking remark phase will erroneously unload that klass.
      
      In this particular crash, while G1 was doing concurrent marking and had prepared its list of
      unreachable classes, JVMTI on a Java thread could traverse classes in the CLD and store
      thread-local JNIHandles for the java_mirror of the loaded classes. G1 did not have knowledge
      of these thread-local JNIHandles, and in the remark phase, it unloaded classes per its prior
      knowledge of unreachable classes. When these JNIHandles were later scanned, it lead to a
      crash.
      
      This fix for JDK-8187577 informs G1's SATB that a klass has been resurrected and should not be
      unloaded.
