Enhancements

security-libs/javax.net.ssl

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.

See JDK-8049321

core-libs/java.lang.invoke

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.

See JDK-8081512

hotspot/runtime

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"

See JDK-8130425

hotspot/compiler

Implemented performance improvements for BigInteger.montgomeryMultiply

We have implemented improvements that will improve performance of several security algorithms, especially when using ciphers with key lengths of 2048-bit or greater. To turn on these improvements, use the options -XX:+UseMontgomeryMultiplyIntrinsic and -XX:+UseMontgomerySquareIntrinsic. This improvement is only for Linux and Solaris on x86_64 architecture.

See JDK-8130150

New Features

deploy/webstart

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.

See JDK-8147627

core-libs

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 8u102 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, an application that does I/O with large multi-megabyte buffers at startup but 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.

See JDK-8147468

core-svc/java.lang.management

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 the InetAddress.getLocalHost() method.

  • Name:

    com.sun.management.jmxremote.host

  • Definition:

    Specifies bind address for default JMX agent. It can be specified via command line while starting JVM or as part of agent config file (management.properties).

  • Value:

    IP address of any network interface of the machine

See JDK-6425769

Changes

javafx/web

Fixed memory leak when Java objects are passed into JavaScript

The bug fix for JDK-8089861, which was first integrated in JDK 8u102, fixes a memory leak when Java objects are passed into JavaScript. Prior to JDK 8u102, the WebView JavaScript runtime held a strong reference to such bound objects, which prevented them from being garbage collected. After the fix for JDK-8089861, the WebView JavaScript runtime uses weak references to refer to bound Java objects. The specification was updated to make it clear that this is the intended behavior. Applications which rely on the previously unspecified behavior might be affected by the updated behavior if the application does not hold a strong reference to an object passed to JavaScript. In such case, the Java object might be garbage collected prematurely. The solution is to modify the application to hold a strong reference in Java code for objects that should remain live after being passed into JavaScript.

See JDK-8089681

security-libs/javax.net.ssl

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.

See JDK-8072463

hotspot/gc

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 with 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, the 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 
        

See JDK-8072725

hotspot/compiler

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.

See JDK-8144957

core-libs/javax.naming

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

Bug Fixes

client-libs
.oracle_jre_usage folder is no longer created in C\Users\myName
Since JDK 1.8.0_60, a folder named .oracle_jre_usage is 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 was created under either C:\Users\\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 JDK-8134300. With this fix, the .oracle_jre_usage folder is created under %ProgramData%/Oracle/Java/.

See JDK-8134300

security-libs/javax.net.ssl

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

See JDK-8149017

hotspot/gc

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.

See JDK-8150518
