Java™ SE Development Kit 8, Update 311 (JDK 8u311)

October 19, 2021

The full version string for this update release is 8u311-b11 (where "b" means "build"). The version number is 8u311.

IANA TZ Data 2021a

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 8u311 are specified in the following table:

JRE Family Version JRE Security Baseline (Full Version String)
8 8u311-b11
7 7u321-b08

Keeping the JDK up to Date

Oracle recommends that the JDK is updated with each Critical Patch Update. In order to determine if a release is the latest, the Security Baseline page can be used to determine which is the latest version for each release family.

Critical patch updates, which contain security vulnerability fixes, are announced one year in advance on Critical Patch Updates, Security Alerts and Bulletins. It is not recommended that this JDK (version 8u311) be used after the next critical patch update scheduled for January 18, 2022.

Java SE Subscription customers managing JRE updates/installs for large number of desktops should consider using Java Advanced Management Console (AMC).

For systems unable to reach the Oracle Servers, a secondary mechanism expires this JRE (version 8u311) on 2022-02-18. 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 23.1.2 JRE Expiration Date in the Java Platform, Standard Edition Deployment Guide.

New Features

 Marlin Renderer in JDK 8u

Starting from version 8u311, the Marlin graphics rasterizer and its artifacts will be built and distributed as a part of the JDK/JRE bundles. It is not the default rendering engine, however there is an option to enable it by setting the following system property:


See JDK-8143849

 Context-specific Deserialization Filter Subset

Allow applications to configure context-specific and dynamically-selected deserialization filters via a JVM-wide filter factory that is invoked to select a filter for each deserialization stream. The behavior is a strict subset of JEP 415: Context-Specific Deserialization Filters to allow a filter factory to be configured using a property configured on the command line or in the security properties file.

The behavior is opt-in based on the presence of the jdk.serialFilterFactory system property on the command line or the jdk.serialFilterFactory security property. If set, the JVM-wide filter factory selects the filter for each stream when the stream is constructed and when a stream-specific filter is set.

The JVM-wide filter factory is a java.util.function.BinaryOperator<sun.misc.ObjectInputFilter> function invoked when each ObjectInputStream is constructed and when the stream-specific filter is set using sun.misc.ObjectInputFilter.Config.setObjectInputFilter(sun.misc.ObjectInputFilter). The parameters are the current filter and a requested filter and the function returns the filter to be used for the stream. When invoked from the ObjectInputStream constructors, the first parameter is null and the second parameter is the static JVM-wide filter. When invoked from sun.misc.ObjectInputFilter.Config.setObjectInputFilter(sun.misc.ObjectInputFilter), the first parameter is the filter currently set on the stream (which was set in the constructor), and the second parameter is the filter requested.

A typical filter factory should use or merge the static JVM-wide filter with other application and context specific filters and the stream-specific filter, if one is set on the stream. The filter factory implementation can also use any contextual information at its disposal, for example, extracted from the application thread context, or its call stack, to compose and combine a new filter. It is not restricted to only use its two parameters.

Refer to Context-Specific Deserialization Filter and Serialization Filtering Guide for details.

Removed Features and Options

 Removed IdenTrust Root Certificate

The following root certificate from IdenTrust has been removed from the cacerts keystore:

+ alias name "identrustdstx3 [jdk]"

  Distinguished Name: CN=DST Root CA X3, O=Digital Signature Trust Co.
See JDK-8225082

Other Notes

 Release Doesn't Correctly Recognize Windows 11

This release doesn't correctly identify Windows 11. The property os.name is set to Windows 10 on Windows 11. In HotSpot error logs, the OS is identified as Windows 10; however, the HotSpot error log does show the Build number. Windows 11 has Build 22000.194 or above.

See JDK-8274840

 Updated the Default Enabled Cipher Suites Preference

The default priority order of the cipher suites for TLS 1.0 to TLS 1.3 has been adjusted.

For TLS 1.3, TLS_AES_256_GCM_SHA384 is now preferred over TLS_AES_128_GCM_SHA256.

For TLS 1.0 to TLS 1.2, some of the intermediate suites have been lowered in priority as follows:

  • Cipher suites that do not preserve forward secrecy have been moved lower in priority than those that do support forward secrecy.
  • Cipher suites that use SHA-1 have been moved lower in priority.

 Modified HttpURLConnection Behavior When a Suitable Proxy Is Not Found

The behavior of HttpURLConnection when using ProxySelector has been modified in this JDK release. HttpURLConnection used to fall back to a direct connection attempt if the configured proxy(s) failed to make a connection. Beginning with this release, the default behavior has been changed to no longer use a direct connection when the first proxy connection attempt fails.

A new system property, sun.net.http.fallbackToDirect, can be set to a value of "true" should an application need to fall back to the old behavior (fall back to a direct connection when the first proxy connection attempt fails).

See JDK-8161016

 System Property to Control Reconstruction of Reference Address Objects by JDK's Built-in JNDI LDAP Implementation

The scope of the com.sun.jndi.ldap.object.trustSerialData system property has been extended to control the deserialization of java objects from the javaReferenceAddress LDAP attribute. This system property now controls the deserialization of java objects from the javaSerializedData and javaReferenceAddress LDAP attributes.

To prevent deserialization of java objects from these attributes, the system property can be set to false. By default, the deserialization of java objects from javaSerializedData and javaReferenceAddress attributes is allowed.

JDK-8267712 (not public)

 Release Doesn't Correctly Recognize Windows Server

This release doesn't correctly identify Windows Server. The property os.name is set to Windows 2019 on Windows Server 2022. In HotSpot error logs, the OS is identified as Windows 10.0 for Windows Server releases 2016, 2019, and 2022; however, the HotSpot error log does show the Build number. Windows Server 2016 has Build 14393 or above, Windows Server 2019 has Build 17763 or above, and Windows Server 2022 has Build 20348 or above.

See JDK-8273229

 SunPKCS11 Initialization With NSS When External FIPS Modules Are in Security Modules Database

The SunPKCS11 security provider can now be initialized with NSS when FIPS-enabled external modules are configured in the Security Modules Database (NSSDB). Before this change, when such a library was configured for NSS in non-FIPS mode, the SunPKCS11 provider would throw a RuntimeException with the message "FIPS flag set for non-internal module".

This change allows the JDK to work properly with recent NSS releases in GNU/Linux operating systems when the system-wide FIPS policy is turned on.

See JDK-8238555

Bug Fixes

This release also contains fixes for security vulnerabilities described in the Oracle Critical Patch Update.
