This update release contains several enhancements and changes including the following.

IANA Data 2015f

JDK 8u65 contains IANA time zone data version 2015f. For more information, refer to Timezone Data Versions in the JRE Software.

Security Baselines

The security baselines for the Java Runtime Environment (JRE) at the time of the release of JDK 8u65 are specified in the following table:

JRE Family Version JRE Security Baseline (Full Version String)
8 1.8.0_65
7 1.7.0_91
6 1.6.0_105

For more information about security baselines, see Deploying Java Applets With Family JRE Versions in Java Plug-in for Internet Explorer.

JRE Expiration Date

The JRE expires whenever a new release with security vulnerability fixes becomes available. Critical patch updates, which contain security vulnerability fixes, are announced one year in advance on Critical Patch Updates, Security Alerts and Third Party Bulletin. This JRE (version 8u65) will expire with the release of the next critical patch update scheduled for January 19, 2016.

For systems unable to reach the Oracle Servers, a secondary mechanism expires this JRE (version 8u65) on February 19, 2016. 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. For more information, see JRE Expiration Date.


When running on OSX 10.11 "El Capitan", when SIP is enabled, certain environment variables intended for debugging applications, such as DYLD_LIBRARY_PATH, may be stripped from the environment when running Java from the command line or when double-clicking a JAR file. Applications should not rely on these variables in a production environment, they are only intended for debugging during development.

New Features and Changes

The following are some of the notable new features and changes in this release:

Support ISO 4217 "Current funds codes" table (A.2)

This enhancement adds support for ISO 4217 table A.2 fund codes. Previously the JDK only supported those currencies listed in table A.1.

See JDK-8074350.

Bug Fixes

This release contains fixes for security vulnerabilities. For more information, see Oracle Java SE Critical Patch Update Advisory.

The following are some of the notable bug fixes included in this release:

Kerberos changes for applications running with security manager

This JDK release introduces some changes to how Kerberos requests are handled when a security manager is present.

Note that if a security manager is installed while a KerberosPricipal is being created, a {@link ServicePermission} must be granted and the service principal of the permission must minimally be inside the {@code KerberosPrincipal}'s realm.

For example, if the result of {@code new KerberosPrincipal("user")} is {@code user@EXAMPLE.COM}, then a {@code ServicePermission} with service principal {@code host/} (and any action) must be granted.

Also note that if a single GSS-API principal entity that contains a Kerberos name element without providing its realm is being created via the org.ietf.jgss.GSSName interface and a security manager is installed, then this release introduces a new requirement. A {@link ServicePermission} must be granted and the service principal of the permission must minimally be inside the Kerberos name element's realm.

For example, if the result of {@link GSSManager#createName(String, Oid) createName("user", NT_USER_NAME)} contains a Kerberos name element {@code user@EXAMPLE.COM}, then a {@code ServicePermission} with service principal {@code host/} (and any action) must be granted. Otherwise, the creation will throw a {@link GSSException} containing the {@code GSSException.FAILURE} error code.

JDK-8048030 (not public)

Hotspot should use PICL interface to get cacheline size on SPARC

The libpicl library is now required on Solaris/SPARC to determine the size of the cache lines. In case the library is not present or the PICL service is not available the JVM will display a warning and compiler optimizations that utilize the BIS (Block Initializing Store) instruction will be turned off.

See JDK-8056124.

Preloading libjsig.dylib causes deadlock when signal() is called

Applications need to preload the libjsig library to enable signal chaining. Previously, on OS X, after libjsig.dylib was preloaded, any call from native code to signal() caused a deadlock. This has been corrected.

See JDK-8072147.

Use Safe Prime Diffie-Hellman Groups

In the JDK SSL/TLS implementation (SunJSSE provider), safe prime Diffie-Hellman groups are used by default. Users can customize Diffie-Hellman groups with the security property, "jdk.tls.server.defaultDHEParameters".

[macosx] JRE AU client installed fails update to NEXTVER on Mac 10.11

A new installer is introduced in the 8u65 release to update OS X users to the latest version. The installer will apply to both scheduled and manual updates, and bundles made available on and OTN. Users who experience compatibility issues with the new installer can manually download and install the ".pkg" installer available on My Oracle Support.

VM crash when class is redefined with Instrumentation.redefineClasses

The JVM could crash when a class was redefined with Instrumentation.redefineClasses(). The crash could either be a segmentation fault at SystemDictionary::resolve_or_null, or an internal error with the message "tag mismatch with resolution error table". This has now been fixed.

See JDK-8076110.

Known Issues

[macosx] Sponsor offer screen accessibility (a11y) issues

Users who operate the keyboard to access user interfaces in the Java installer will be unable to access hyperlinks and checkboxes in software add-on offer screens. As a workaround to setting preferences related to add-on software in the user interface, users can disable such offers either by disabling them in the Java Control Panel, or by passing 'SPONSORS=0' via the command line.
