It can be specified via command line while starting JVM or as part of agent config file (management.properties). Specifies bind address for 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. *New JMX agent property - jmxremote.host* A new property, .host, is introduced that specifies the bind address for the default JMX agent. New system property for the remote JMX connector Applications that do I/O using direct buffers will not see any benefit to using this system 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 with certain patterns of I/O usage may benefit from using this property. If the property is not set, then no limit is put on the size of buffers that are cached. The value of the property is the maximum capacity of a direct buffer that can be cached. The system property 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 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.Ībility to limit the capacity of buffers that can be held in the temporary buffer cache This improvement is only for Linux and Solaris on x86_64 architecture.ģ2/64-bit interoperability in Java Web Start To turn on these improvements, use the options -XX:+UseMontgomeryMultiplyIntrinsic and -XX:+UseMontgomerySquareIntrinsic. We have implemented improvements that will improve performance of several security algorithms, especially when using ciphers with key lengths of 2048-bit or greater. Implemented performance improvements for BigInteger.montgomeryMultiply The problem has been observed only when JVM is started from JNI code in which TLS is declared using "_thread" Users can set this flag in one of two ways: This gives the reaper thread a bigger stack size, so for a large TLS size, such as 32k, the process will not fail. To overcome this issue, we have introduced a workaround ( ) in which the user can set the reaper threads stack size to a default instead of to 32768. When a large TLS size is set, it steals space from the threads stack, which eventually results in a stack overflow. The reason for this behavior is that the reaper thread was created with a low stack size of 32768k. When a large TLS (Thread local storage) size is set for Threads, the JVM results in a stack overflow exception. The functionality it used to provide, namely anonymous class loading with possible constant pool patches, is available via the fineAnonymousClass() method. Note that this extension does not apply to TLS 1.1 and previous versions. The SHA224withDSA and SHA256withDSA algorithms are now supported in the TLS 1.2 "signature_algorithms" extension in the SunJSSE provider. Support SHA224withDSA and SHA256withDSA in the SunJSSE provider MSI Enterprise JRE Installer option, REMOVEOLDERJRES, does not remove static installs. MSI Enterprise JRE Installer option, REMOVEOLDERJRES For more information, see JRE Expiration Date. After either condition is met (new release becoming available or expiration date reached), the JRE will provide additional warnings and reminders to users to update to the newer version. This JRE (version 8u102) will expire with the release of the next critical patch update scheduled for October 19, 2016.įor systems unable to reach the Oracle Servers, a secondary mechanism expires this JRE (version 8u102) on November 19, 2016. Critical patch updates, which contain security vulnerability fixes, are announced one year in advance on Critical Patch Updates, Security Alerts and Third Party Bulletin. The JRE expires whenever a new release with security vulnerability fixes becomes available. JRE Security Baseline(Full Version String)
