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 8u51) will expire with the release of the next critical patch update scheduled for October 20, 2015.

For systems unable to reach the Oracle Servers, a secondary mechanism expires this JRE (version 8u51) on November 20, 2015. 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.

New Features and Changes

Ephemeral DH keys less than 768 bits deactivated

JDK-8076328 (not public).


Operating system's restricted environment (Native Sandbox)

JDK 8u51 introduced the following changes to Native Sandbox:

  • Native sandbox is available on Windows platform only.

  • Native sandbox can be enabled or disabled through Java Control Panel->Advanced settings->Enable the operating system's restricted environment (native sandbox) or by setting deployment.security.use.native.sandbox property to true in deployment.properties file.

    Native sandbox is disabled by default.

  • When native sandbox is enabled, the sandbox applets or web-start applications will run in a restricted environment, that is provided by the operating system. This will not affect the all-permission applications and they will continue to run as before.

  • Native sandbox will be disabled for applications included the in Exception Site List (ESL) or when Deployment Rule Set (DRS) is used.

  • Sandbox applets deployed with HTML applet tag which includes all-permissions JAR files from the Class-Path manifest attribute, will run in native sandbox.

    In such cases, a special warning dialog will display, informing the user that the applet may not work properly, when such an applet tries to access the all-permission JAR files.

  • Custom preloader will be disabled in certain cases when native sandbox is enabled:

    • Custom preloader will be disabled when sandbox applets or web-start applications are initializing and the default preloader will be used instead. After application is initialized, Java VM restarts with native sandbox enabled and the custom preloader will be used.
    • For all-permission applications, custom preloader will be disabled if it is located in the JNLP file with sandbox permission, until user agrees to run application from the Security Dialog, which grants unrestricted access (privileged) to application.

JDK-8071699 (not public)

Area: security-libs/javax.net.ssl
Synopsis: Deprecate RC4 in SunJSSE provider

RC4 is now considered as a weak cipher. Servers should not select RC4 unless there is no other stronger candidate in the client requested cipher suites. A new security property, jdk.tls.legacyAlgorithms, is added to define the legacy algorithms in Oracle JSSE implementation. RC4 related algorithms are added to the legacy algorithms list.

JDK-8043201 (not public)

Area: security-libs/javax.net.ssl
Synopsis: Prohibit RC4 cipher suites

RC4 is now considered as a compromised cipher. RC4 cipher suites have been removed from both client and server default enabled cipher suite list in Oracle JSSE implementation. These cipher suites can still be enabled by SSLEngine.setEnabledCipherSuites() and SSLSocket.setEnabledCipherSuites() methods.

JDK-8043202 (not public)

Area: security-libs/javax.net.ssl
Synopsis: Improved certification checking

With this fix, JSSE endpoint identification does not perform reverse name lookup for IP addresses by default in JDK.

If an application does need to perform reverse name lookup for raw IP addresses in SSL/TLS connections, and encounter endpoint identification compatibility issue, System property "jdk.tls.trustNameService" can be used to switch on reverse name lookup. Note that if the name service is not trustworthy, enabling reverse name lookup may be susceptible to MITM attacks.

Known Issues

Area: deploy/plugin
Synopsis: Java issue with Firefox 38, long delay with MyD loading

Java Plugin is unable to obtain proxy settings from Firefox 38 due to a bug in Mozilla framework. It may cause a long delay during RIA start up or can even cause start up failures. See the related issue:

https://bugzilla.mozilla.org/show_bug.cgi?id=1165286

According to Mozilla, Firefox 39 will contain a fix for this problem.

Workarounds:

  • Use another supported browser
  • Downgrade browser to Firefox 37
  • Specify proxy settings in JCP (NOT in "Browser settings")

JDK-8081459 (not public)


Area: deploy
Synopsis: JNLP files won't launch from IE11 on Windows 10 Creators Update

Web-start applications cannot be launched when clicking JNLP link from IE 11 on Windows 10 Creators Update when 64-bit JRE is installed. Workaround is to uninstall 64-bit JRE and use only 32-bit JRE.
