RELEASE NOTES:

deploy/webstart:

    JDK-8055448: Set 32 or 64 bit JRE requirements in a JNLP file

      Web Start applications can now specify requested JREs with their arch attributes, and select
      the first one available that matches, even if it is not the same arch (32 bit vs 64 bit) as
      the currently running JRE. For example, the JNLP content below would place first preference on
      64 bit JDK8, and if not available, 32 bit JDK9: ```  <resources arch="x86_64">      <java
      version="1.8"/> </resources> <resources arch="x86">     <java version="1.9"/> </resources> ```
      Note that in the above example, in order to launch a 64 bit 1.8 JRE, a 64 bit 9 JRE must be
      installed. If only a 32 bit 9 JRE is installed, the 64 bit 1.8 JRE is unavailable.

    JDK-8147627: 32/64-bit interoperability in Java Web Start

      The ability to specify a preference to launch a Java Web Start application in 64-bit or 32-bit
      architectures is now supported, by adding the 'arch' attribute to the JNLP resources block.

core-libs/java.lang.invoke:

    JDK-8081512: Internal package sun.invoke.anon has been removed

      The internal package sun.invoke.anon has been removed. The functionality it used to provide,
      namely anonymous class loading with possible constant pool patches, is available via the
      Unsafe.defineAnonymousClass() method.

core-libs/javax.naming:

    JDK-8149450: Improved exception handling for bad LDAP referral replies

      The JDK was throwing a NullPointerException when a non-compliant REFERRAL status result was
      sent but no referral values were included. With this change, a NamingException with message
      value of "Illegal encoding: referral is empty" will be thrown in such circumstances. See
      JDK-8149450 and JDK-8154304 for more details

hotspot/compiler:

    JDK-8144957: Removed PICL warning message

      In 8u40, and 7u80, a new feature was introduced to use the PICL library on Solaris to get some
      system information. If this library was not found, we printed an error message:
      
      Java HotSpot(TM) Server VM warning: PICL (libpicl.so.1) is missing. Performance will not be
      optimal. 
      
      This warning was misleading. Not finding the PICL library is a very minor issue, and the
      warnings mostly lead to confusion. In this release, the warning was removed.

security-libs/javax.net.ssl:

    JDK-8149017: Fix to resolve "Unable to process PreMasterSecret, may be too big" issue

      Recent JDK updates introduced an issue for applications that depend on having a delayed
      provider selection mechanism. The issue was introduced in  JDK 8u71, JDK 7u95 and JDK 6u111.
      The main error seen corresponded to an exception like the following : ``` handling exception:
      javax.net.ssl.SSLProtocolException: Unable to process PreMasterSecret, may be too big ```

    JDK-8049321: Support SHA224withDSA and SHA256withDSA in the SunJSSE provider

      The SHA224withDSA and SHA256withDSA algorithms are now supported in the TLS 1.2
      "signature_algorithms" extension in the SunJSSE provider.  Note that this extension does not
      apply to TLS 1.1 and previous versions.

core-svc:

    JDK-8134300: .oracle_jre_usage folder no longer created in C:\Users\myName

      Since JDK 1.8.0_60, a folder named .oracle_jre_usage gets created in the home directory. This
      folder and the files inside it are created by the Java Runtime Environment to track the last
      time a JRE was used. This information is very important in understanding what JRE
      installations are currently being used on the system.
      
      On Windows, this folder gets created under either `C:\Users\<username>\AppData\Local or
      C:\Users\myName\AppData\Roaming` depending upon whether the user is local, or is a network
      user.
      
      Writing content in this folder over the network on Windows can introduce performance overhead.
      This problem has been fixed with bug JDK-8134300. With this fix .oracle_jre_usage folder gets
      created under `%ProgramData%/Oracle/Java/` 

core-libs/java.nio:

    JDK-8147468: Ability to limit the capacity of buffers that can be held in the temporary buffer cache

      The system property `jdk.nio.maxCachedBufferSize` has been introduced in <version> to limit
      the memory used by the "temporary buffer cache". The temporary buffer cache is a per-thread
      cache of direct memory used by the NIO implementation to support applications that do I/O with
      buffers backed by arrays in the java heap. The value of the property is the maximum capacity
      of a direct buffer that can be cached. If the property is not set then no limit is put on the
      size of buffers that are cached. Applications with certain patterns of I/O usage may benefit
      from using this property. In particular if an application does I/O with large multi-megabyte
      buffers at startup but therefore does I/O with small buffers may see a benefit to using this
      property. Applications that do I/O using direct buffers will not see any benefit to using this
      system property.

core-svc/javax.management:

    JDK-6425769: New system property for the remote JMX connector

      New JMX agent property - `jmxremote.host`   A new property,
      `com.sun.management.jmxremote.host`, is introduced that specifies the bind address for the
      default JMX agent. If the latter is not specified, the default JMX agent will listen on all
      interfaces (0.0.0.0) and the host value placed in the agent service URL (JMXServiceURL) is the
      IP address returned from invocation of `InetAddress.getLocalHost()` method.
      
      * Name: `com.sun.management.jmxremote.host` * Definition : Specifies the bind address for the
      default JMX agent. It can be specified via the command line while starting the JVM or as part
      of the agent config file (`management.properties`). * Value: IP address of any network
      interface of the machine

hotspot/runtime:

    JDK-8130425: New property jdk.lang.processReaperUseDefaultStackSize

      When a large TLS (Thread local storage) size is set for Threads, the JVM results in a stack
      overflow exception. The reason for this behavior is that the reaper thread was created with a
      low stack size of 32768k. When a large TLS size is set, it steals space from the threads
      stack, which eventually results in a stack overflow. This is a known glibc bug. To overcome
      this issue, we have introduced a workaround (jdk.lang.processReaperUseDefaultStackSize) in
      which the user can set the reaper threads stack size to a default instead of to 32768. This
      gives the reaper thread a bigger stack size, so for a large TLS size, such as 32k, the process
      will not fail. Users can set this flag in one of two ways: 1.
      -Djdk.lang.processReaperUseDefaultStackSize=true 2.
      System.setProperty("jdk.lang.processReaperUseDefaultStackSize", "true")
      
      The problem has been observed only when JVM is started from JNI code in which TLS is declared
      using "__thread" 

security-libs/java.security:

    JDK-8141540: Comodo Root CA removed

      The Comodo "UTN - DATACorp SGC" root CA certificate has been removed from the cacerts file.

    JDK-8072463: Modify requirements on Authority Key Identifier extension field during X509 certificate chain building

      The requirement to have the Authority Key Identifier (AKID) and Subject Key Identifier (SKID)
      fields matching when building X509 certificate chains has been modified for some cases.

hotspot/gc:

    JDK-8150518: With UseG1GC, specifying -XX:ParallelGCThreads=0 is no longer allowed

      With UseG1GC, specifying -XX:ParallelGCThreads=0 is no longer allowed. Previously, with
      -XX:ParallelGCThreads=0, G1 would execute some tasks using serial code executed by the VM
      thread. The closest approximation of this behavior is to specify -XX:ParallelGCThreads=1,
      which causes parallel tasks to be executed by a single GC worker thread using parallel code.

    JDK-8072725: Providing more granular levels for GC verification

      This enhancement provides a way to specify more granular levels for the GC verification
      enabled using the "VerifyBeforeGC", "VerifyAfterGC" and "VerifyDuringGC" diagnostic options.
      It introduces a new diagnostic option VerifySubSet using which one can specify the subset of
      the memory system that should be verified. 
      
      With this new option, one or more sub-systems can be specified in a comma separated string.
      Valid memory sub-systems are: threads, heap, symbol_table, string_table, codecache,
      dictionary, classloader_data_graph, metaspace, jni_handles, c-heap and codecache_oops.  
      During the GC verification, only the sub-systems specified using VerifySubSet get verified: 
      ``` D:\tests>java -XX:+UnlockDiagnosticVMOptions -XX:+VerifyBeforeGC
      -XX:VerifySubSet="threads,c-heap" -Xlog:gc+verify=debug Test [0.095s][debug  ][gc,verify]
      Threads [0.099s][debug  ][gc,verify] C-heap [0.105s][info   ][gc,verify] Verifying Before GC
      (0.095s, 0.105s) 10.751ms [0.120s][debug  ][gc,verify] Threads [0.124s][debug  ][gc,verify]
      C-heap [0.130s][info   ][gc,verify] Verifying Before GC (0.120s, 0.130s) 9.951ms
      [0.148s][debug  ][gc,verify] Threads [0.152s][debug  ][gc,verify] C-heap ``` If any invalid
      memory sub-systems are specified with VerifySubSet, Java process exits with the following
      error message: ``` D:\tests>java -XX:+UnlockDiagnosticVMOptions -XX:+VerifyBeforeGC
      -XX:VerifySubSet="threads,c-heap,hello" -Xlog:gc+verify=debug oom Error occurred during
      initialization of VM VerifySubSet: 'hello' memory sub-system is unknown, please correct it ```
