Security Baselines

The security baselines for the Java Runtime Environment (JRE) at the time of the release of JDK 8u101 are specified in the following table:

JRE Family Version JRE Security Baseline (Full Version String)
8 1.8.0_101-b13
7 1.7.0_111-b13
6 1.6.0_121-b09

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 8u101) will expire with the release of the next critical patch update scheduled for October 19, 2016.

For systems unable to reach the Oracle Servers, a secondary mechanism expires this JRE (version 8u101) on November 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.

Improve access control to javax.rmi.CORBA.ValueHandler

The javax.rmi.CORBA.Util class provides methods that can be used by stubs and ties to perform common operations. It also acts as a factory for ValueHandlers. The javax.rmi.CORBA.ValueHandler interface provides services to support the reading and writing of value types to GIOP streams. The security awareness of these utilities has been enhanced with the introduction of a permission"enableCustomValueHanlder"). This is used to establish a trust relationship between the users of the javax.rmi.CORBA.Util and javax.rmi.CORBA.ValueHandler APIs.

The required permission is "enableCustomValueHanlder" SerializablePermission. Third party code running with a SecurityManager installed, but not having the new permission while invoking Util.createValueHandler(), will fail with an AccessControlException.

This permission check behaviour can be overridden, in JDK8u and previous releases, by defining a system property, "jdk.rmi.CORBA.allowCustomValueHandler".

As such, external applications that explicitly call javax.rmi.CORBA.Util.createValueHandler require a configuration change to function when a SecurityManager is installed and neither of the following two requirements is met:

  1. The"enableCustomValueHanlder") is not granted by SecurityManager.
  2. In the case of applications running on JDK8u and before, the system property "jdk.rmi.CORBA.allowCustomValueHandler" is either not defined or is defined equal to "false" (case insensitive).

Please note that the "enableCustomValueHanlder" typo will be corrected in the October 2016 releases. In those and future JDK releases, "enableCustomValueHandler" will be the correct SerializationPermission to use.

Support added to jarsigner for specifying timestamp hash algorithm

A new -tsadigestalg option is added to jarsigner to specify the message digest algorithm that is used to generate the message imprint to be sent to the TSA server. In older JDK releases, the message digest algorithm used was SHA-1. If this new option is not specified, SHA-256 will be used on JDK 7 Updates and later JDK family versions. On JDK 6 Updates, SHA-1 will remain the default but a warning will be printed to the standard output stream.

See JDK-8038837


MSCAPI KeyStore can handle same-named certificates

Java SE KeyStore does not allow certificates that have the same aliases (

However, on Windows, multiple certificates stored in one keystore are allowed to have non-unique friendly names. The fix for JDK-6483657 makes it possible to operate on such non-uniquely named certificates through the Java API by artificially making the visible aliases unique.

Please note, this fix does not enable creating same-named certificates with the Java API. It only allows you to deal with same-named certificates that were added to the keystore by 3rd party tools.

It is still recommended that your design not use multiple certificates with the same name. In particular, the following sentence will not be removed from the Java documentation: "In order to avoid problems, it is recommended not to use aliases in a KeyStore that only differ in case."


See JDK-6483657


DomainCombiner will no longer consult runtime policy for static ProtectionDomain objects when combining ProtectionDomain objects

Applications which use static ProtectionDomain objects (created using the 2-arg constructor) with an insufficient set of permissions may now get an AccessControlException with this fix. They should either replace the static ProtectionDomain objects with dynamic ones (using the 4-arg constructor) whose permission set will be expanded by the current Policy or construct the static ProtectionDomain object with all the necessary permissions.

Known Issues


JRE 8u101 is not recognized by Internet Explorer (IE) when using static class ID

When a static class id is used to launch an applet or web start application while using JRE 8u101, users will get an unwanted dialogue box stating that they either use the latest JRE or cancel the launch even though they have installed and are using the latest JRE (JRE 8u101).

This specific case is only applicable on Windows and IE.

We do not recommend using static class id for JRE version selection (since JDK 5u6, Dec 2005) per

To work around this issue, users can do one of the following two things:

  1. Hit launch with the latest version (8u101) and ignore the warning.
  2. Install JRE 8u102 instead of JRE 8u101 to avoid this issue.

To address this issue, developers can do one of the following two things:

  1. Use a dynamic class id instead of static class id.
  2. Use java_version when using an HTML applet or a JNLP descriptor when using JNLP.
